The development of semiconductor-based surface-enhanced Raman scattering (SERS) substrates is often hindered by their limited sensitivity. Crystal facet engineering has been recognized as an effective strategy to improve the SERS performance of semiconductors. However, the underlying mechanism by which different exposed facets influence SERS activity in bimetallic oxide systems remains unexplored. In this study, we successfully synthesized NiCo 2 O 4 and ZnCo 2 O 4 bimetallic oxides with distinct exposed facets by regulating the alkali source. When evaluated using 4-Nitrothiophenol (4-NBT) as a probe molecule, the {110} facet demonstrated the highest SERS activity in both oxide systems. The enhancement factors (EF) reached 5.56 × 10 4 for NiCo 2 O 4 and 7.41 × 10 4 for ZnCo 2 O 4 . The limit of detection (LOD) was as low as 10 −7 M and 10 −8 M, respectively, as well as the excellent repeatability and stability. Energy level structure reveals that the superior SERS properties on the {110} facet can attributed to their higher VB maxima, which enhances the thermodynamic driving force and kinetic efficiency of the interfacial charge transfer (CT) process. Moreover, first-principles calculations further illustrate that the CT efficiency on the {110} facet can be effectively improved. This work provides a clear new direction for designing high-performance semiconductor SERS substrates through precise facet control.

Transition metal oxides exhibit inherent catalytic activity for ammonium perchlorate (AP) decomposition; however, their performance is limited by the scarcity of accessible active sites and low conductivity. Therefore, morphology-directed structural design and interfacial engineering are highly desirable. In this study, two-dimensional (2D) MCo 2 O 4 nanosheets ( M = Fe, Ni, Cu, and Cr) were synthesized via a thermal expansion method and subsequently combined with three types of carbon materials C x (C x = rGO, CNTs, and g-C 3 N 4 ) to construct 2D MCo 2 O 4 /C x composites. Structural analyses demonstrate that the intimate interfacial coupling between 2D MCo 2 O 4 nanosheets and carbon materials effectively suppresses restacking and establishes a continuous conductive network. More importantly, strong interfacial coupling enables effective electronic modulation at the heterojunction, resulting in an optimized charge distribution and enhanced interfacial electron transfer. Among all catalysts, 5 wt. % FeCo 2 O 4 /rGO-1 demonstrates the most notable catalytic activity for AP decomposition, reducing its peak temperature in the high-temperature decomposition stage by 137.4 °C and increasing its heat release by 736.33 J·g⁻ 1 . Electrochemical tests confirm that accelerated interfacial charge transfer enhances AP pyrolysis. Kinetic modelling, TG-FTIR-MS, and DFT calculations indicate that the 2D-2D heterointerface boosts the adsorption of the AP intermediate NH 3 and promotes its conversion into higher-valence NO 2 , while also accelerating electron transport and lowering the decomposition barrier. The synergistic effect between interfacial electron transport and the heterojunction promotes the rapid AP degradation. Based on these findings, a plausible catalytic mechanism for AP decomposition is proposed.

The rational design of hierarchical Co-Ni-Fe-based inorganic materials is of great significance for functional electrochemical applications. Here, a self-supported Co2(OH)2CO3@CoFe-LDH hierarchical heterostructure was constructed in-situ on a conductive nickel foam substrate via a one-step hydrothermal method. A prominent structural feature is that Co2(OH)2CO3 nanoneedles are uniformly and radially anchored on the surfaces of CoFe-LDH nanosheets, which effectively suppresses nanoneedle aggregation. By systematically tuning the Co2+/Fe3+ molar ratio, the effects of composition on phase selectivity, nucleation behavior, and morphological evolution in the multimetallic system were elucidated. The results reveal that CoFe-LDH nanosheets preferentially form at moderate Co2+/Fe3+ ratios, whereas further increasing the Co2+ content leads to heterogeneous nucleation of excess Co2+ species on the LDH surface and induces the directional growth of Co2(OH)2CO3, thereby giving rise to the hierarchical heterostructure. The resulting self-supported electrode exhibits stable oxygen evolution reaction performance under alkaline conditions. In situ Raman spectroscopy reveals a potential-dependent surface reconstruction, evidenced by the attenuation of precursor-related metal-oxygen vibrations and the formation of (oxy)hydroxide species at the heterointerfaces, highlighting the correlation between multimetallic composition regulation and interfacial structural evolution.

Solar-driven CO 2 reduction is confronted with challenges of limited light absorption and elevated reaction energy barriers. To address these, a solvothermal-wet coupled chemical reduction method was developed to precisely construct a bifunctional catalyst comprising single-atom Ru and clustered Ni on porous CeO 2 nanorods, featuring efficient CO 2 methanation in H 2 O vapor under concentrated solar irradiation (4.01 W·cm −2 ). Through lattice substitution at Ce sites, Ru single atoms form a distinctive pentacoordinate configuration, largely accelerating H 2 O dissociation to generate active hydrogen (*H). Conversely, Ni clusters enhance visible-to-near-infrared light capture via localized surface plasmon resonance effects, optimizing the CO 2 adsorption configuration to reduce the activation energy barrier of the C=O bond. The synergistic interplay between these dual sites, mediated by the hydrogen spillover effect, resolves the spatiotemporal mismatch between proton supply and carbon source activation. Based on the evidence from femtosecond and nanosecond transient absorption spectroscopy, the Ru/Ni dual-active sites enable spatially decoupled directional transport of charge carriers, synergistically handling the photogenerated carrier transfer dynamics. Furthermore, the robust photoelectric and thermal effects induced by concentrated irradiation enhance photogenerated carrier concentrations and the reaction temperature, reducing the apparent activation energy for CH 4 formation to 14.61 kJ·mol −1 (a 29.9% decrease compared to non-concentrated systems). This catalyst achieves a CH 4 production rate of 133.1 μmol·cm −2 ·h −1 (a 31-fold enhancement over non-concentrated systems) and a solar-to-chemical energy conversion efficiency of 0.423%, offering insights into the design of photothermal synergistic catalytic systems through atomic-scale active site decoupling and multi-physical field coupling.

The simultaneous management of charge separation and surface reaction energetics remains a pivotal challenge in the development of efficient photocatalysts for hydrogen production. Herein, we report a dual‑functional interfacial engineering strategy by constructing an S‑scheme heterojunction between nickel‑cobalt Prussian blue analogues (Ni–Co PBAs) and metallic Borophene (Bp). The optimized Ni–Co PBAs/Bp composite achieves an exceptional hydrogen evolution rate of 56.04 mmol g −1 over 5 h in an Eosin Y‑sensitized system under visible light, surpassing its individual components by factors of 29 and 4.4, respectively. Integrated in situ spectroscopic and DFT analyses unveil a synergistic mechanism: Bp not only serves as a charge‑transfer mediator to enable efficient S‑scheme electron flow driven by a built‑in electric field, but also acts as an electronic modulator to upshift the d‑band center of Ni/Co sites, thereby optimizing hydrogen adsorption free energy. This work provides a concrete blueprint for developing high‑performance photocatalysts via co‑optimizing macroscopic charge dynamics and atomic‑scale site reactivity for solar fuel production.

Noninvasive wearable glucose sensors capable of real-time sweat analysis offer a less discomforting alternative for long-term monitoring in patients with diabetes. However, practical implementation remains challenging. Major barriers include insufficient catalytic sensitivity to quantify the low glucose levels in sweat, limited compatibility between nanomaterial synthesis and scalable manufacturing processes, and the lack of a biofluid microenvironment suitable for enzyme-free electrochemical sensing. Here, we address these challenges by combining strong interfacial anchoring on a conductive template with surfactant-assisted growth control to engineer high-aspect-ratio (∼100) 1D Ni-TCPP MOF nanofibers as an active shell on MXene-NH2. In contrast to conventional electrospinning-assisted approaches, the resulting 1D MOF shell is polymer-template-free and thus avoids insulating scaffold components. The resulting fluffy, self-supporting Ni-MOF@MXene architecture is inherently compatible with printed electronics, enabling large-area fabrication of wearable enzyme-free glucose-sensing patches. To overcome the constraints of enzyme-free sensing in physiological biofluids, we further develop an integrated system that combines microfluidics with a NaOH/Nafion/PVA alkaline sustained-release membrane, establishing a localized alkaline microenvironment within sweat to enable continuous analysis.

Solution-reduced nano-Mg is uniformly dispersed in flower-like Ni/C(D). • Mg 2 Ni/Mg 2 NiH 4 pump and carbon confinement synergistically enhance kinetics. • 100% capacity retention over 90 cycles after activation. A rationally designed Mg-Ni/C(D) composite was synthesized by calcining a hydrothermally prepared Ni-MOF(BDC) precursor (from Ni 2 + and terephthalic acid, H 2 BDC) into flower-like porous Ni/C(D), followed by Mg loading via lithium-naphthalenide reduction. Spherical Ni/C(T) was prepared similarly using trimesic acid (H 3 BTC). Compared with Ni/C(T), Ni/C(D) possesses an effective hierarchical porous structure, enabling a higher effective reversible hydrogen storage capacity (based on the total composite mass) at a comparable dehydrogenation onset temperature. During hydrogen sorption, in situ-formed Mg 2 Ni acts as a reversible Mg 2 NiH 4 /Mg 2 Ni hydrogen pump, lowering the kinetic barrier and providing nucleation sites for the Mg/MgH 2 transformation, while the carbon matrix confines nanoparticles to prevent agglomeration. Notably, after 10 activation cycles, it retains nearly 100% capacity over the next 90 cycles. This synergy between catalytic pumping and nanoconfinement makes Mg-Ni/C(D) promising for solid-state hydrogen storage.

This work demonstrates a rational strategy for designing high-performance Mg-based hydrogen storage materials.

The effects of catalyst preparation and reaction conditions, feedstocks, and catalyst reusability were investigated. • The morphologies of catalyst evolution from sheet-like structures to nanorods were controlled by hydrothermal treatment. • Morphology control is associated with metal-support interactions and promotes selective ring opening. • Rod-like Ni@La 2 O 2 CO 3 delivers a remarkable 76.9 ± 0.3% yield of 1,5-pentanediol from furfuryl alcohol. • DFT calculations indicate that the catalyst favors the 1,5-PeD pathway with a low barrier of 1.46 eV and an exothermicity of –0.53 eV. The selective hydrogenolysis of biomass-derived furfuryl alcohol (FA) to 1,5-pentanediol (1,5-PeD) represents a sustainable alternative to petrochemical routes, yet achieving high selectivity over non-noble metal catalysts remains a significant challenge due to competing side reactions. Herein, we report an efficient catalyst featuring Ni nanoparticles supported on rod-like lanthanum oxycarbonate (Ni@La 2 O 2 CO 3 ). Under optimized preparation and reaction conditions, the catalyst achieves complete FA conversion and a remarkable 1,5-PeD yield of 76.9 ± 0.3%, with a moderately high space-time yield (STY) of 1.13 ± 0.01 g 1,5-PeD ·g cat –1 ·h –1 . The morphological evolution from sheet-like structures to nanorods via controlled hydrothermal treatment significantly correlates with the interfacial synergy between Ni and La 2 O 2 CO 3 and boosts the 1,5-PeD yield. Density functional theory (DFT) calculations further elucidate the mechanistic origin of the high regioselectivity, identifying an interface that induces electron accumulation on the Ni active sites. This electronic modulation significantly lowers the activation barrier for the C–O bond cleavage of the tetrahydrofurfuryl alcohol intermediate to 1.46 eV for the 1,5-PeD pathway, compared to 1.72 eV for the 1,2-PeD route. This work provides an efficient strategy for the rational design of morphology-controlled non-noble catalysts for the high-value valorization of biomass.

Urea-assisted electrolytic water splitting for hydrogen production represents an effective contemporary strategy for generating green hydrogen. The sluggish kinetics of the anodic urea oxidation reaction (UOR) and cathodic hydrogen evolution reaction (HER) limit their practical application. The MXene quantum dots (MQDs) promote pronounced d-d orbital hybridization between Ni and Mo sites. The constructed heterostructures facilitate electron transfer and modulate charge redistribution. The extensive formation of heterostructures between numerous quantum dots and nickel molybdate results in the emergence of flower-like clusters at the tips of rod-like NiMoO 4 particles. The augmentation of the specific surface area results in the exposure of a larger quantity of active sites, which facilitates the redistribution of charge across these active sites, consequently enhancing the hydrolytic activity. The electrocatalyst exhibits remarkable performance in both the UOR and HER, achieving 1.31 V and 55 mV at 10 mA cm –2 , respectively. The catalyst for urea–assisted water electrolysis requires only 1.38 V at 10 mA cm –2 . The prepared catalyst can be employed for seawater splitting and photovoltaic-driven hydrogen production. In-situ Raman spectrum confirms that Ni sites on the NiMoO 4 /MQDs surface transform into Ni–OOH under hydrolysis and subsequently govern the hydrolytic reaction. This work indicates that d-d orbital hybridization can provide pathways for electronic transitions, thereby enhancing charge-transfer efficiency and effectively lowering reaction energy barriers.

Bamboo biomass was valorized into functional carbon microspheres for electrode design. • Bamboo-derived carbon induced self-assembly of Ni–Co–Mg hydroxide nanostructures. • Mg incorporation strengthened the LDH–carbon interaction and structural stability. • The optimized NCM@BC-20 electrode delivers 1226.8 F g −1 at 1 A g −1 . • The assembled ASC achieves 63.16 Wh kg −1 with 89.1% retention after 6000 cycles. Bamboo is an abundant and fast-growing lignocellulosic resource with considerable potential as a sustainable precursor for functional carbon materials. In this work, bamboo-derived carbon microspheres were employed to induce the self-assembly of Mg-modulated Ni-Co layered hydroxide heterostructures, forming a hierarchical composite electrode denoted as NCM@BC. During synthesis, the carbon microspheres acted not only as conductive supports but also as heterogeneous nucleation sites for hydroxide growth, leading to an open architecture that facilitated electrolyte penetration and charge transport. Meanwhile, Mg incorporation regulated the local coordination environment of the Ni-Co hydroxide phase and improved the structural stability of the layered framework during repeated redox reactions. As a result, the optimized NCM@BC-20 electrode delivered a specific capacitance of 1226.8 F g −1 at 1 A g −1 with favorable rate capability. Furthermore, the assembled asymmetric supercapacitor, using NCM@BC-20 as the positive electrode and activated carbon as the negative electrode, operated over a 1.6 V voltage window, achieved an energy density of 63.16 Wh kg −1 at 800 W kg −1 , and retained 89.1% of its peak capacitance after 6000 cycles. These results demonstrate that bamboo biomass can be converted into a value-added carbon component that not only directs heterostructure formation but also contributes to enhanced electrochemical performance, providing a practical route for the development of sustainable carbon-based electrode materials.

Highlights A novel PS-2-AB chelating resin was synthesized by grafting 2-aminobenzimidazole onto polystyrene. The resin showed Cu(II) and Ni(II) adsorption capacities of 125.04 mg/g and 157.44 mg/g, respectively. The resin maintained over 84% adsorption capacity after five regeneration cycles. To address heavy metal contamination in wastewater, this study developed a novel chelating resin (PS-2-AB) by grafting 2-aminobenzimidazole onto chloromethylated polystyrene. The resin was characterized using SEM, BET, FTIR, and XPS to confirm successful modification and analyze its structural properties. Batch adsorption tests were conducted to evaluate its removal performance for Cu(II) and Ni(II) ions. Under optimal conditions (pH 5.0–7.0, dosage: 1.0 g/L), PS-2-AB achieved maximum adsorption capacities of 125.04 mg/g for Cu(II) and 157.44 mg/g for Ni(II), which are significantly higher than those of the commercial resin D113 (44.68 mg/g for Cu(II) and 25.17 mg/g for Ni(II)) under the same conditions. Adsorption kinetics followed the pseudo-second-order model, indicating chemisorption-dominated behavior, while equilibrium data fit the Langmuir model, suggesting monolayer adsorption. Thermodynamic parameters confirmed a spontaneous and endothermic process. After five regeneration cycles, PS-2-AB retained approximately 87% (Cu) and 89% (Ni) of its original capacity, demonstrating good reusability. These results indicate that PS-2-AB exhibits markedly better adsorption performance than D113, making it a promising and cost-effective adsorbent for the efficient removal of Cu(II) and Ni(II) from aqueous media.

The poor dispersion and stability of metal-doped carbon materials prepared via conventional hydrothermal or calcination methods have limited their application in advanced oxidation processes (AOPs). Herein, inspired by a hot-spot-effect-triggered confined coordination strategy, we developed a coconut shell biochar-supported Cu–Ni catalyst (Cu–Ni@BC) for peroxymonosulfate (PMS) activation to degrade multiple antibiotics, including tetracycline hydrochloride (TCH), ciprofloxacin (CIP), and norfloxacin (NOR). The mechanochemical synthesis endowed the catalyst with a high specific surface area, uniform metal dispersion, and strong metal–support interaction, ensuring stable loading and excellent catalytic activity. Under optimal conditions, the Cu–Ni@BC+PMS system achieved 96.7% TCH removal within 30 min, markedly outperforming single-metal systems. Radical quenching experiments and EPR analysis identified O 2 •⁻ as the predominant reactive species, with additional contributions from •OH, ¹O 2 , and SO 4 •⁻, collectively indicating a synergistic radical/non-radical mechanism. The catalyst retained high activity over five cycles (TCH removal efficiencies of 97.1%, 96.0%, 92.7%, 86.9%, and 82.3%), with minimal Cu and Ni leaching. Toxicity evaluation confirmed significant detoxification of TCH and its intermediates. Moreover, the catalyst displayed high degradation efficiencies for CIP (95.7%) and NOR (85.6%), excellent performance in real wastewater, and strong anti-interference tolerance toward common inorganic anions, achieving 85.6–96.9% removal for diverse antibiotics and dyes. This study overcomes the performance bottleneck of traditional single-metal catalysts in PMS activation and provides new insights into designing efficient, stable, and sustainable bimetal–biochar catalytic materials.
