The development of the petrochemical industry necessitates the treatment of oily industrial wastewater. Addressing the separation, recovery, and reuse of oily wastewater with low-cost, high-efficiency, and environmentally friendly methods has become a significant focus in environmental protection. The search for oil-water separation materials with specific functionality and environmental durability is now a priority. In this study, natural wood was delignified, and ZnO nanoparticles were grown within the wood aerogel to create a functionalized nano-composite wood aerogel. The porous ZnO/DW aerogels exhibited an average adsorption capacity of 17.66 g g −1 . Due to the presence of a hydration shell formed by hydrogen bonding, the water-saturated ZnO/DW aerogel exhibits hydrophilic and oleophobic properties. The separation device achieved a water flux of 39,400 L m −2 h −1 and a separation efficiency of over 98.5 %, effectively facilitating oil-water separation. Furthermore, the synergistic effect of ZnO nanoparticles and wood aerogels resulted in the photocatalytic degradation of methylene blue in solution by up to 92.94 %. The cycle tests show the excellent stability of the sample in compression-release cycle, adsorption-extrusion cycle and photocatalytic degradation cycle.

In this study, ZnO/TiO 2 nanosheets were synthesized using a hydrothermal method followed by annealing. The resulting hierarchical ZnO–TiO 2 heterostructures exhibited improved gas-sensing performance compared with pure ZnO. We demonstrated that tuning the ratio of Zn to Ti components in the heterostructure allowed us to adjust the sensor stability , with the best- performing sample having a Zn:Ti ratio of 2:1. A notable reduction was observed in both the sensor response and recovery times, down to 22 and 17 s, respectively, by utilizing nanosheet- structured ZnO/TiO 2 heterojunctions. To gain insight into the interaction between the sensing materials and formaldehyde (HCHO) molecules, we performed first-principles calculations to examine the density of states , charge transfer, and energy of adsorption. Our approach to constructing heterogeneous structures contributes to overcoming the low desorption efficiency and slow response-recovery time of pure ZnO for gas-sensing applications.

In the context of the ongoing development of artificial intelligence and 5G technologies, a growing number of sensors are being integrated into the daily lives. Self-powered wearable sensors based on triboelectric nanogenerator (TENG) represent an innovative solution to this trend, but the output performance of the flexible TENGs remains suboptimal. In this study, the band-matched calcium titanate (CaTiO 3 ) and zinc oxide (ZnO) nanostructures are prepared to form CaTiO 3 /ZnO (CTO/ZnO) Schottky heterojunctions. The heterojunctions are subsequently doped into organic ferroelectric polyvinylidene fluoride (PVDF) to create flexible composite film, which significantly increases the dielectric constant through space charge polarization. Then the CTO/ZnO-PVDF composite films served as triboelectric materials of the CaTiO 3 /ZnO-PVDF-based TENG (CZP-TENG). After optimizing the molar ratio of ZnO to CTO in heterojunction and weight ratio of CTO/ZnO in PVDF, both the output voltage and current density of the TENG are significantly improved, exhibiting a power density of 106.6 mW m −2 . Finally, the CZP-TENG powers light–emitting diodes and a temperature sensor, serves as a wearable sensor, and enables self-powered human body sensing, particularly in gait recognition for preventing of movement-related diseases and injury rehabilitation.

The photo-responded behavior of ZnO and its sensing response to ethylene or acetone under visible-light irradiation at room temperature were reported. A ZnO sensor without any response to target gas in the air atmosphere in dark at room temperature, exhibits not only a photo response but also an obvious sensing response to target gas in the air atmosphere under visible-light irradiation. It is suggested that the non-intrinsic photo-absorption induced by the native defects of ZnO (i.e., the two-photon or multi-photon excitation process via the intraband) may be responsible for the photo-responded behavior to the visible light . Moreover, a mechanism model that accounts for the solid-state process of photo-carrier generation/recombination is proposed to explain the photo-induced gas sensing response of ZnO under visible-light irradiation. This indicates that the photo-activated gas sensing response property of semi-conductor can be also caused by its non-intrinsic photo-absorption.

We systematically studied the influences of annealing atmosphere on the structural and optical properties of Al-doped ZnO (AZO) powders by performing anneals in N 2 , Ar 2 , H 2 and O 2 atmospheres. The results indicated that the optical properties were highly influenced by the annealing atmosphere, which were more pronounced for the AZO powders annealed in forming gas and an oxygen atmosphere. The E 1 (LO) vibration mode in the Raman spectra exhibits a good correlation with the green emission and is demonstrated to be originated from V O defects. We conclude that both V O and O i defects give rise to the green photoluminescence in ZnO, and each will play a dominant role in oxygen-deficient and oxygen-rich environments, respectively.

A novel environment-friendly all oxide semiconductor Cu 2 O/ZnO heterojunction was first applied in photoelectrochemical biosensing. The heterojunction was prepared by facile two-steps of electrodeposition and characterized by scanning electron microscopy, X-ray diffractometry, and ultraviolet and visible spectrophotometer. The enhancement of photocurrent is attributed to the rapid and efficient electron transition and the inhibition of photo-induced electron–hole pairs recombination, which stems from the formation of energy level matching Cu 2 O/ZnO heterojunction. Using glutathione (GSH) as a model, the fabricated photoelectrochemical sensor showed good performances with a rapid response, facile preparation, wide concentration range, excellent stability and low detection limit (0.8 μmol L −1 ). It had been successfully applied to the detection of GSH in glucose injection and the result agreed well with that given in the instruction. This strategy opened a new channel for Cu 2 O/ZnO heterojunction in photoelectrochemical sensing.

Sandstone buildings in humid environments are highly susceptible to fungal colonization, which poses a significant threat to the buildings’ preservation. Therefore, the development of coatings with antimicrobial properties is essential to protect these structures. This study demonstrates the antifungal activity and durability of amphiphobic and UV-absorbing F-ZnO/SiO 2 (FZS) coatings. We show that the coating efficiently inhibits the growth of Aspergillus niger , protecting the sandstone surface from one of the most common molds. A fungal inhibition rate of up to 94 % was achieved with FZS nanocomposite concentrations >0.30 % (g/L). To ensure consistent antifungal performance along with enhanced water repellency and durability under practical conditions, a concentration of 0.37 % was selected for the FZS coating. Accelerated aging tests revealed that the coated sandstone retained its antifungal activity for over 56 days under harsh environmental conditions, exhibiting an antifungal effect 800 % greater than that of uncoated sandstone. After 70 days, the coating still retained its water repellency. These results underscore the potential of the coating for long-term protection of sandstone relics, offering durability and ease of maintenance for real-world applications.

2,4,6-Trinitrotoluene (TNT), as a widely used energetic material, is prone to causing water pollution during its production, transportation and disposal processes. This poses a severe menace to the environment and human health. Therefore, the efficient treatment of TNT-polluted wastewater has grown into a popular research direction in the environmental field. Photocatalytic technology has great application prospects due to its environmental friendliness and thorough degradation. As a commonly used photocatalyst, nano-ZnO suffers from the drawbacks of a wide band gap that only responds to ultraviolet light and limited photocatalytic performance, and constructing heterojunctions is an effective strategy to enhance its performance. In this study, CdS/ZnO heterojunction composites were synthesized via the coprecipitation method. After optimizing the component ratio, the 4-CdS/ZnO exhibited a photocatalytic degradation efficiency of over 92% for TNT, with a degradation efficiency 20 times higher than that of pure ZnO. Moreover, cyclic experiments verified its excellent stability. The present study puts forward novel ideas and technical support for the green and efficient degradation of TNT-contaminated water bodies.

Piezoelectric nanogenerators based on the piezoelectric effect have attracted widespread attention. With the advancement of wearable piezoelectric nanogenerators, particularly the continuous expansion of their application scenarios, greater demands are being placed on the flexibility and piezoelectric output of nanogenerator devices. Herein, to address this issue, silver-decorated zinc oxide nanorods were prepared and incorporated into P(VDF-TrFE) to fabricate a flexible composite material with excellent piezoelectric performance. Zinc oxide nanorods were first grown via a hydrothermal method, followed by the successful decoration with silver nanoparticles through visible-light-induced self-assembly. Upon constructing an Ag/ZnO heterojunction, the polarization charges within the zinc oxide (ZnO) nanorods undergo directional migration toward the Ag nanoparticles under mechanical strain. This charge transfer behavior significantly amplifies the macroscopic piezoelectric output of the Ag/ZnO nanorod-embedded P(VDF-TrFE) composite, leading to a marked enhancement in its overall piezoelectric performance. Optimally, at a doping concentration of 7.5 wt%, the composite achieves an output voltage of approximately 17.5 V and a current of about 0.4 μA, which are approximately 2.3 times and 1.2 times those of pure P(VDF-TrFE) film, respectively. This outstanding output enables the PENG to be applied in monitoring various human motions. This work offers a fresh perspective on material design, opening up new avenues for the development of high-performance PENGs.

Chronic diabetic wounds are characterized by persistent infection, oxidative stress, and moisture imbalance. However, effectively managing these concurrent pathological factors within the complex wound microenvironment remains a significant clinical challenge. Herein, we report the development of a multifunctional Janus nanofibrous membrane via sequential electrospinning of a thymol (THY)-incorporated hydrophilic polyacrylonitrile (PAN)/polyvinylpyrrolidone (PVP) layer and a zinc oxide (ZnO)-incorporated hydrophobic polylactic acid (PLA) layer, integrating structural bioinspiration with organic–inorganic synergy for comprehensive microenvironment management. By mimicking the desert beetle’s elytra, the membrane exhibits asymmetric wettability (the hydrophilic side shows a water contact angle (WCA) dropping to 0° within 0.37 s), enabling autonomous and unidirectional exudate transport (hydrostatic pressure difference: 52 mm) to prevent exudate accumulation. Importantly, the system capitalizes on a “permeabilization–penetration” synergy between THY and ZnO: THY disrupts bacterial membranes, facilitating the infiltration of Zn2+ to eradicate pathogens. The system achieves nearly 100% antibacterial efficiency against Escherichia coli and Staphylococcus aureus while exhibiting significant antioxidant activity, as evidenced by an 86% 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging rate. In vivo evaluations in a diabetic mouse model confirmed that the Janus membrane significantly accelerates wound closure through enhanced re-epithelialization and organized collagen deposition, achieving 78.04% wound closure on day 4 and near-complete closure by day 14, thereby outperforming all control groups. In summary, this “all-in-one” Janus platform enables precise microenvironment regulation through the integrated control of interfacial moisture and multipathway therapeutic relief.

It is demanding to exploit highly efficient ethanol sensors due to the malign irritating effects and explosion risks. This paper reports an excellent ethanol sensor based on metal–organic frameworks (MOFs)-derived Ag@ZnO nanoparticles (NPs). Specifically, 1.25 wt% Ag@ZnO sensor exhibits a ninefold improvement of response at 230 ℃ (~ 120, to 100 ppm ethanol), besides the short response time (~ 5 s) and a low theoretical detection limit (35 ppb). We propose that the optimized Ag dopant boosts sensing performances due to the electronic/chemical sensitization effects, besides the increased oxygen vacancies and nano-heterojunctions. The superior sensitivity and selectivity of the innovative ZIF-8 derived Ag@ZnO sensors may provide a valuable reference for promising ethanol sensing applications.
