MOF-derived ZnO/ZCS heterojunction for CIP degradation. • Quasi-Type-I alignment overcome by interfacial built-in electric field. • 94.66% CIP removal under visible light in 120 min. • Singlet oxygen identified as dominant reactive species. • Stable performance in tap water and surface water. Ciprofloxacin (CIP) resists biodegradation and accumulates in aquatic environments, threatening ecosystems and human health. Herein, a ZIF-8-derived ZnO/Zn 0.5 Cd 0.5 S (ZnO/ZCS) heterojunction photocatalyst was fabricated via a hydrothermal-calcination method. The composite inherits a high specific surface area of 36.05 m 2 ·g –1 from the MOF precursor, while the loaded Zn 0.5 Cd 0.5 S narrows the band gap to 2.52 eV (vs. 3.18 eV for ZnO) and extends the photoresponse to ∼550 nm. XPS binding energy shifts confirm interfacial charge redistribution and a built-in electric field that drives directional carrier separation, overcoming the recombination limitation inherent to the quasi-Type-I alignment. Under visible-light irradiation, the optimal 35% ZnO/ZCS achieves 94.66% CIP removal within 120 min (k = 1.85 × 10 –2 min –1 ), markedly outperforming pristine ZnO and ZCS (both <60%). It retains >80% efficiency after five consecutive cycles and >60% removal in tap/surface water across a wide pH range (2.323–9.653). Radical trapping and EPR experiments verify the generation of 1 O 2 , •OH, h + , and •O 2 – , with 1 O 2 identified as the dominant reactive species. LC-MS analysis reveals piperazine ring oxidation and methylation as the initial degradation steps. This work provides a robust MOF-derived heterojunction strategy for efficient photocatalytic antibiotic remediation. Download: Download high-res image (357KB) Download: Download full-size image

HPCS-stabilized lignin nanoparticles enhanced natamycin solubility and stability. • Gelatin/ZnO films incorporated with LNPs showed superior mechanical and barrier properties. • Films exhibited synergistic photothermal and ROS-mediated antibacterial activity. • Lignin shielded natamycin from degradation, balancing stability and antibacterial efficacy. • Coating extended sweet potato shelf life and showed favorable biodegradability. To address the poor photostability and low aqueous solubility of natamycin (N), a hydroxypropyl chitosan (HPCS)-stabilized lignin nanoparticle (LNP) delivery system (LNP-N/HPCS) was developed in this study. The results showed that the nanocarriers exhibited a high encapsulation efficiency (89.17 ± 2.8%) and a moderate loading efficiency (11.63 ± 0.1%), while significantly increasing the solubility of natamycin to 13.5 times that of its free form at room temperature. Structural analysis indicated that LNP-N/HPCS formed stable core–shell-like nanostructures through hydrogen bonding, van der Waals forces, and π–π interactions, enabling efficient loading and stable dispersion. Furthermore, the delivery system was incorporated into gelatin/ZnO composite films (Gel/ZnO/LNPs) to construct multifunctional active packaging materials. The resulting composite film exhibited good antioxidant activity, mechanical properties, and gas barrier properties. After 10 min of xenon lamp irradiation, the composite film rapidly heated to 54.6 °C. After 150 min of irradiation, 67.55% of the initial natamycin content remained in the Gel/ZnO/LNPs5 composite film, whereas the retention rate of free natamycin was only 24.72%, indicating that the LNP delivery system improved the photostability of natamycin. In addition, the composite system exhibited good antibacterial activity in both film-forming solutions and solid films. In particular, Gel/ZnO/LNPs5 exhibited nearly complete growth inhibition against Escherichia coli , Staphylococcus aureus , and Dickeya dadantii E36 after 10 min of light irradiation, and achieved an inhibition rate of approximately 85% against Fusarium solani-melongenae 24–3. After 150 min of continuous irradiation, the Gel/ZnO/LNPs5 film still exhibited an inhibition rate of 55.67% against Fusarium solani-melongenae 24–3. Practical application results showed that the composite film could delay quality deterioration of sweet potatoes during storage to some extent and gradually disintegrated within approximately 6 days in soil. In addition, no significant inhibitory effect was observed in the seed germination test. Overall, this study provides an effective strategy for developing multifunctional food packaging materials with photothermal responsiveness, light-enhanced antimicrobial activity, and postharvest preservation functions.

Dual-functional ZnO/LIG sensor made via 1-step laser direct writing. • Combines sensitive NTC temperature sensing and efficient Joule heating. • Exhibits high sensing linearity (R 2 = 0.9988) and max TCR of −3.65%. • Rapid heating rate of 2.68 °C s −1 at 24 V with electrothermal stability. • Zigzag design enables high bending durability and multi-site monitoring. Traditional flexible temperature sensors and heaters often suffer from discrete architectures, delayed thermal responses, and poor stability. To address these limitations, a zigzag-patterned dual-function ZnO/LIG sensor featuring independently operable temperature sensing and Joule heating functions is fabricated via one-step laser direct writing on a ZnCl 2 -doped polyimide (PI) film. This induces the in-situ growth of ZnO nanoparticles within a three-dimensional LIG scaffold, constructing a hierarchical porous structure that enhances electron transport and interfacial heat transfer. Fundamentally, first-principles DFT calculations verify strong interfacial orbital hybridization, which modulates carrier behaviors and significantly improves thermoresistive responses. Consequently, the device demonstrates stable negative temperature coefficient (NTC) characteristics (20–80 °C) with excellent linearity (R 2 =0.9964), a total relative resistance change of −3.65%, and an average temperature coefficient of resistance (TCR) of −0.061 °C −1 . It simultaneously exhibits efficient Joule heating, achieving 2.68 °C s⁻¹ at 24 V with stable temperature elevation during stepwise cycling. The zigzag electrode architecture effectively releases deformation stress, ensuring reliable baseline resistance without significant degradation after repeated bending cycles. Ultimately, this synergistic optimization accurately captures minute variations for precise body temperature mapping, respiration monitoring, and rapid deicing, providing a cost-effective, scalable strategy for flexible thermal-control equipment.

Metal migration strategy construct oxygen-bridged Zn-SAC/ZnO sub-nanocluster catalyst. • Catalyst attains full PET conversion, 90.7% BHET yield and high Zn space-time yield. • N-anchoring endows catalyst maintains 91.7% initial activity after multiple cycles. • The catalyst shows a wide applicability to diverse waste PET. • DRIFTS and DFT reveal atomic-level synergistic activation at Zn-SAC-cluster interface. Designing and constructing multi-site, highly active and stable heterogeneous glycolysis catalysts to convert polyethylene terephthalate (PET) into monomers is an important strategy for achieving sustainable plastic closed-loop recycling. Herein, we prepared an oxygen-bridged Zn single-atom and ZnO sub-nanocluster catalyst by “metal atoms surface migration strategy”. The optimized catalyst achieves nearly 100% PET conversion and bis (hydroxyethyl)terephthalate (BHET) yield of above 90.7% within 1.5 h, with its Zn active sites delivering a BHET space-time yield of 198.9 mmol BHET g Zn −1 h −1 . Owing to the robust anchoring by N-dopants, the catalyst retains 91.7% of its initial activity after multiple cycles. In-situ infrared and density functional theory (DFT) calculations revealed that the excellent catalytic performance of the catalyst is attributed to the synergistic effect of Zn single-atom and oxygen-bridged ZnO sub-nanocluster, which jointly promote the dual activation of the ethylene glycol hydroxyl group and the PET ester bond. This work emphasizes an atomic-scale engineering approach to maximize the density, accessibility, and stability of active sites, offering a viable idea for efficient plastic chemical recycling.

In Cu 2 ZnSn(S, Se) 4 (CZTSSe) solar cells, the conventional magnetron-sputtered ZnO (ZnO-SP) suffers from high cost, low efficiency, and interface damage. This study systematically compares sol–gel ZnO (ZnO-SG) and 18C6 crown ether-modified sol–gel ZnO (ZnO-SG-18C6) as interfacial layers. X-ray diffraction (XRD), scanning electron microscope (SEM), AFM, and X-ray photoelectron spectroscopy (XPS) show ZnO-SP has a uniform hexagonal wurtzite structure, whereas ZnO-SG displays an amorphous fibrous morphology with bright/dark striations. Both exhibit similar UV absorption peaks, but ZnO-SG shows broader absorption and double-exponential decay. Density–voltage ( J – V ) tests reveal that ZnO-SG-18C6 increases PCE from 8.5% to 10.6%, surpassing the 9.5% achieved with ZnO-SP. Electrochemical impedance spectroscopy (EIS) analysis shows that the ZnO-SG-18C6 layer reduces carrier recombination, with the charge transfer resistance ( R ct ) increasing by 30%. Transient photocurrent measurements further reveal that it enhances the photocurrent response, achieving a 1.8-fold increase in the peak, which rises to four times under a 70% high duty cycle.This work demonstrates ZnO-SG-18C6 as a low-cost, high-efficiency alternative to ZnO-SP in CZTSSe solar cells.

Carbon monoxide is a colorless and odorless, highly toxic gas, posing a significant risk to both human health and industrial safety. Zinc oxide has garnered significant interest for its outstanding chemical stability and cost-effectiveness in the development of CO sensors. However, sensors based on a single ZnO has the shortcomings of low sensitivity and high detection limit, rendering them challenging to meet the precise detection requirements for CO. To address this issue, ZnO nanoflower arrays were prepared by chemical bath deposition (CBD), followed by modification of varying ratios of Co 3 O 4 and NiO onto the ZnO nanoflower arrays. The response value of the sensor based on Co 3 O 4 -NiO/ZnO-2 to 100 ppm CO was 104% at 310 °C. Remarkably, the sensor achieved an exceptionally low detection limit of 1 ppb. Further, the crystal structure and morphology characteristics of Co 3 O 4 -NiO/ZnO were systematically analyzed by XRD, SEM, TEM, XPS, Raman, EDS, EPR, and BET. The results show that the improvement in gas-sensing performance is mainly ascribed to the ZnO nanoflower array and the heterojunctions formed among Co 3 O 4 , NiO and ZnO. In this study, Co 3 O 4 and NiO decorated ZnO nanoflower arrays were prepared by a two-step CBD, offering a novel approach for advancing high-performance CO sensors.

Perovskite nanocrystals (NCs) are promising color converters for displays but are limited by defect-related inefficiency and instability. To address this, a one-pot synthesis is developed in which ZnO NCs and oleic acid first form stable zinc oleate complexes that anchor onto the surface of CsPbBr 3 NCs, thereby creating a stable organic-inorganic ligand shell, which suppresses degradation and Ostwald ripening during processing. Theoretical calculations confirm that the introduction of ZnO enhances the stability of NCs by raising the formation energy and suppressing defect generation. Consequently, photoluminescence quantum yield (PLQY) is boosted to 97%, representing a dramatic increase from the 32.4% value of pristine CsPbBr 3 NCs. Employing these high-performance NCs, a white light-emitting diode (WLED) was fabricated by integrating the composite film with a blue LED chip. More importantly, the NC-based composite films demonstrate robust stability under thermal, aqueous, and optical stresses, retaining > 70% of their initial PL intensity—significantly outperforming control samples (<30%). This WLED exhibits a wide color gamut, covering 129.8% of the NTSC standard and 96.9% of Rec. 2020. Subsequently, a WLED array backlight unit was fabricated and subsequently integrated into a prototype display. This work establishes the practical potential of ZnO-incorporated CsPbBr 3 NCs as efficient and stable color-conversion materials, thereby paving the way for advancing high-performance backlit display technology.

This study successfully fabricated a freestanding ZnO@(NiFe)OOH nano-heterostructure array electrocatalyst with high hydrophilicity for efficient electrocatalytic nitrate reduction to ammonia (NO 3 RR) in neutral media. The material integrates the large specific surface area of one-dimensional ZnO nanoarrays with the electronic modulation capability of heterogeneous interfaces, which significantly enhances nitrate adsorption and activation, promotes proton supply, and effectively suppresses the hydrogen evolution side reaction. The highly hydrophilic surface further accelerates electrolyte diffusion, nitrate ion transport, and product desorption. In a neutral electrolyte of 0.1 M PBS containing 0.15 M KNO 3 at a potential of −1.0 V (vs. RHE), the catalyst achieves an ammonia production rate of 4.86 mg·h −1 ·cm −2 with a Faradaic efficiency of 85.58%, while generating minimal byproducts, demonstrating excellent catalytic selectivity and stability. This work provides a new strategy for the structural design and performance enhancement of NO 3 RR electrocatalysts, which holds significance for advancing green ammonia synthesis and enabling efficient conversion of nitrate in water pollution control. Graphical A self-supported ZnO@(NiFe)OOH core-shell array enables efficient nitrate-to-ammonia conversion. The ZnO core accelerates NO 3 -diffusion and prevents active site coverage while enhancing conductivity and stability. The (NiFe)OOH shell facilitates intermediate conversion and suppresses hydrogen evolution by weakening H+ adsorption. Its surface hydroxyl groups promote water dissociation, ensuring a local proton supply. In neutral media, this design achieves superior performance: at −1.0 V vs RHE in 0.15 M KNO 3 , it delivers an NH3 yield of 4.86 mg h −1 cm −2 and a faradaic efficiency of 85.58%.

Single-atoms (SAs) supported on inorganic materials have been confirmed as effective active sites in catalytic chemical reaction. For metal oxide semiconductor (MOS) based gas sensors, the core is the catalytic reaction process of gas molecules with adsorbed active oxygens on sensing materials. In order to prepare gas sensing material with high performance, herein, we reported highly atomically dispersed Pt functionalized oxygen vacancies enriched ZnO nanowires (Pt 1 /ZnO-O v ) via simple impregnation method. Gas sensing tests revealed that Pt 1 /ZnO-O v based gas sensor exhibits a high N 2 H 4 sensing performance. Pt SAs on ZnO increase the number of active sites, resulting in high response, good selectivity and rapid response speed to N 2 H 4 gas. N 2 H 4 -TPR and N 2 H 4 -TPD tests showed that Pt 1 /ZnO-O v has stronger oxygen and N 2 H 4 adsorbability. In addition, DFT results indicated that the oxygen vacancies on ZnO-O v facilitate Pt atoms incorporation into surface Zn sites, and Pt incorporation promotes N 2 H 4 adsorption across the sensor. In a word, enriched oxygen vacancies ZnO nanowire decorated with atomically dispersed Pt is an efficient sensing material for selective detection of N 2 H 4 .

Photocatalytic removal of trace methane at room temperature is hindered by low partial pressure, weak adsorption, and sluggish C H bond activation. Here, anatase T(100), T(101), and their ZnO-modified counterparts were evaluated in a closed CH 4 /air system containing approximately 400 ppm CH 4 . Under the standard humidification protocol, the measured inlet water-vapor concentration was 30,900 ± 600 ppmv (3.09 ± 0.06 vol%). ZnO modification enhanced apparent CH 4 removal, reaching 91.70 ± 0.49% for 10%ZnO-T(101) after 1 h of UV irradiation. The 5%ZnO samples were selected for mechanistic comparison because they retained a more pronounced facet-associated difference. HRTEM and UV-Raman confirm the presence of nanoscale crystalline ZnO domains in intimate contact with anatase TiO 2 . PL, transient photocurrent, and EIS indicate improved charge separation and interfacial transport for 5%ZnO-T(101), while TPD, XPS O 1 s, and EPR support weaker retention of CO 2 /carbonate-related species and stronger light-induced ·OH and ·O 2 − signals. At approximately 1000 ppm CH 4 , 10%ZnO-T(101) achieved a CH 4 conversion of 78.46 ± 0.57%, a CO 2 mineralization yield of 60.78 ± 0.50%, and a gas-phase carbon closure of 85.43 ± 0.50%. CO 2 accounted for 77.47 ± 0.68% of converted carbon and CO for 3.96 ± 0.31%; the unclosed 14.57% carbon fraction may include low-abundance oxygenated intermediates, surface-associated carbon species, and analytically unresolved trace products. Four humid-state cycles retained 97.56 ± 0.24% of the initial activity. These results highlight facet-associated ZnO/TiO 2 contact effects involving improved charge utilization, H 2 O/O 2 activation, and product-species regulation.

Background Malondialdehyde (MDA) is a pivotal oxidative stress biomarker implicated in cardiovascular diseases, neurodegeneration, and cancer; however, its trace quantification in complex biological matrices remains analytically daunting. Photoelectrochemical (PEC) sensing offers inherently low background noise and exceptional sensitivity for trace bioanalysis. Nevertheless, efficiently translating molecular recognition into amplified PEC signals remains a challenge. Results We report a nanoconfinement-mediated PEC interface that integrates covalent molecular conjugation with plasmonic amplification within a crystalline matrix scaffold. Within this nanoconfined environment, localized Au nanoparticles serve as plasmonic amplifiers that anchor 4-aminothiophenol (4-ATP) receptors. Upon MDA recognition, the optimized sensor exhibits dual linear detection ranges spanning 0.001 to 1.0 nmol L −1 ( R 1 2 = 0.9928) and 1.0 to 1000 nmol L −1 ( R 2 2 = 0.9992), yielding an ultralow detection limit of 0.3 pmol L −1 . Significance The confined Schiff-base reaction between 4-ATP and MDA generates an interfacial reaction product, leading to a new absorption band at approximately 450 nm and modulation of the Au LSPR band. This change is mainly attributed to the altered local dielectric environment around Au NPs. Wavelength-dependent operando transient photovoltage spectroscopy (TPV) provides mechanistic evidence that plasmon-driven hot-carrier injection augments PEC signal output. Overall, this work establishes an interface-engineering paradigm that integrates molecular conjugation with plasmonic coupling, offering a promising blueprint for the PEC detection of small-molecule biomarkers.

Ferroelectric polymers are promising candidates for flexible energy harvesting owing to their piezoelectricity, low density, flexibility, and environmental compatibility. Herein, P(VDF-TrFE) composite films containing ZnO nanoparticles and carboxylated multi walled carbon nanotubes (CMWCNTs) were prepared, and their structure and electrical properties were regulated by hot rolling. ZnO nanoparticles acted as heterogeneous nucleating agents to promote β-phase formation, while CMWCNTs enhanced dielectric response through the microcapacitor effect. The optimized composite contained 1.08 wt% ZnO and 0.02 wt% CMWCNTs. With increasing rolling temperature, molecular orientation was progressively improved, and the film rolled at 90°C exhibited an orientation degree of 0.66, high β-phase fraction, remanent polarization of 22 μC cm −2 , piezoelectric coefficient of 46 pC N −1 , and relative dielectric constant of 19.4. A piezoelectric triboelectric nanogenerator based on this film delivered a maximum output voltage of 31 V and a power density of 15.3 μW cm −2 . This work clarifies how ZnO nucleation, CMWCNT assisted dielectric regulation, and hot rolling induced orientation jointly modulate the structure and output performance of P(VDF-TrFE) based ternary composite films.
