Methyl orange degradation under UV-A showed comparable initial activity for optimized electrostatic deposition (pH 7–8) and UAD, demonstrating that performance is governed not only by ZnO loading but also by dispersion and accessibility of active sites. Despite higher loading near the ZnO point of zero charge, pH 7 coatings contained larger agglomerates and does not exhibited higher activity. Reusability tests showed progressive deactivation of electrostatically deposited ZnO, consistent with insufficient long-term adhesion, whereas UAD composites maintained stable activity over repeated cycles.

Overall, combining plasma activation with UAD yields robust, durable ZnO/polymer composites suitable for reusable photocatalytic surfaces.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148237647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of the coassembly approach provides an additional level of complexity for molecular engineering. Specifically, metabolite coassembly represents a versatile and sustainable approach for constructing tunable supramolecular architectures that merge the elegance of biological self-organization with the functionality of advanced materials. This review summarizes recent developments in understanding the fundamental principles, mechanisms, and applications of metabolite-based coassemblies. Cooperative noncovalent interactions, such as hydrogen bonding, π–π stacking, hydrophobic, and electrostatic interactions, govern the hierarchical organization of simple bio-derived molecules into nanostructures, including fibers, sheets, gels, and vesicles. By precisely tuning molecular ratios, solvent conditions, and environmental stimuli, these assemblies exhibit remarkable control over morphology, stability, and functionality. The resulting supramolecular systems display tunable optical, mechanical, and electronic properties, enabling diverse applications in biomedicine, catalysis, sensing, drug delivery, and environmental remediation. Importantly, the inherent biocompatibility, abundance, and chemical simplicity of metabolites underscore their promise as sustainable building blocks for next-generation soft materials. This review also discusses emerging challenges and future opportunities in rationally designing metabolite-based coassemblies to achieve adaptive, stimuli-responsive, and multifunctional materials, providing a roadmap toward sustainable and intelligent supramolecular systems inspired by nature.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148166914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we present a synergistic strategy combining fluorine engineering with conductivity modulation to significantly enhance both the stability of RuO2. RuO2 nanoparticles (≈3 nm in diameter) were prepared via a sol–gel method and supported on carbon nanotubes (CNTs) to form a RuO2/CNT composite, which was subsequently fluorinated at 200°C to obtain RuO2/CNT-F. Systematic investigations reveal that F incorporation modulates the electronic structure of RuO2 and mitigates proton accumulation during OER, while the conductive CNT matrix facilitates efficient charge transfer. The optimized RuO2/CNT-F catalyst exhibits exceptional acidic OER activity, requiring an overpotential of only 209 mV to achieve a current density of 10 mA cm−2 in 0.5 M H2SO4, along with remarkable stability exceeding 300 h in a three-electrode system. Notably, the catalyst also demonstrates outstanding durability in a PEM electrolyzer, maintaining stable operation for over 2000 h at 10 mA cm−2 and sustaining an industrially relevant current density of 500 mA cm−2 for 50 h. This work provides an effective strategy for designing high-performance acidic OER catalysts through synergistic electronic modulation and nanostructure engineering.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148166915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we develop an N-doped CuO catalyst supported on nickel foam (N-CuO/NF) through a facile molten-salt route followed by controlled annealing. The optimized catalyst exhibits enhanced kinetics for eNO3RR, reduced charge-transfer resistance, and an increased electrochemically active surface area. Remarkably, Cl− incorporation into the electrolyte establishes a synergistic interaction between Cl−-mediated anodic oxidation and the coexisting Cu0/Cu2+ sites on the optimal N-CuO/NF-3h. This synergy enables simultaneous achievement of high nitrate-removal efficiency (>90%) and high N2 selectivity (~90%) in an undivided cell. Mechanistic investigations indicate that anodically generated hypochlorous acid (HOCl) oxidizes cathodically produced NH4+ to N2, effectively suppressing ammonia accumulation. Moreover, N-CuO/NF-3h demonstrates outstanding cycling stability over four consecutive cycles, with minimal activity loss (<8%) and maintained structural integrity. This work underscores the dual role of N-doping in modulating the electronic structure of CuO and the pivotal role of Cl− in steering the reaction pathway toward N2 formation. The findings offer a practical strategy for selective nitrate-to-N2 conversion in wastewater treatment.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 6","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148166916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, biofuels, particularly biodiesel, stand out as a biocompatible and friendly option. However, biodiesel production via transesterification generates large quantities of glycerol (GOL) as a by-product. GOL is recognized as one of the top 10 value-added chemicals derived from biomass, yet its crude contains impurities that make purification costly and environmentally challenging. This has driven extensive research into converting crude GOL directly into high-value products. This study examines the conversion of GOL into four major products, glyceraldehyde, dihydroxyacetone, 1,3-propanediol, and glyceric acid, summarizing selectivity and conversion data for each. The broad industrial applications of these products, spanning the polymer, food, pharmaceutical, cosmetics, and other industries, are also outlined. This review uniquely provides an integrated insight into chemical, electrochemical, photochemical, and biocatalytic systems, with particular emphasis on enzyme catalysis immobilized on metal–organic frameworks (MOFs). Given that key GOL-derived products are obtained through oxidation pathways, special attention is given to the natural catalyst Laccase, which, in combination with the mediator 2,2,6,6-tetramethyl-1-piperidine-N-oxyl (TEMPO), can oxidize GOL into value-added compounds such as glyceraldehyde and glyceric acid. The critical review of the literature suggests that enzyme catalysis represents a more sustainable approach, offering high selectivity in GOL oxidation and enhanced environmental compatibility, as biocatalysts are inherently nontoxic and eco-friendly.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnma.202500632","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148078795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, challenges such as polyiodide shuttling, side reactions, and Zn dendrite growth hinder their further deployment. Herein, a composite hydrogel electrolyte composed of a sodium alginate (SA) matrix and halloysite nanotubes (HNTs) as the reinforcing component is rationally designed via a cation-induced crosslinking strategy. The SA matrix, which is rich in hydrophilic functional groups, exhibits strong Zn2+ affinity and I3− repulsion. Furthermore, the oppositely charged inner and outer surfaces of one-dimensional HNTs endow the hydrogel with fast and selective Zn2+ transport pathways, leading to high ion conductivity (22.32 mS cm−1) and transference number ( <math></math>= 0.67). The synergistic ion-regulation strategy ensures uniform Zn2+ flux and efficient I3− fixation. Thereby, the Zn anode demonstrates an ultralong plating/stripping life of 1100 h. Moreover, the Zn–I2 cells with the composite hydrogel electrolyte retain a high capacity of 122.1 mAh g−1 after 5000 cycles at 4 A g−1 (capacity retention of 86.7%). The proposed approach enables the facile fabrication of functional hydrogels from earth-abundant minerals and polymers, offering a sustainable solution for aqueous Zn–I2 batteries.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"12 5","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148073593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
