Coupling the electrochemical oxidative upgrading of formaldehyde (FOR) with hydrogen evolution reaction (HER) toward energy-efficient H2 production and simultaneous chemical is important, but it still faces huge challenges. Herein, a unique hierarchical heterojunction designed by coupling Ni(OH)2 nanosheet S-modified Ni species on nickel foam substrate (S–Ni@Ni(OH)2/NF) via two-step strategy. The nanosheets large surface area contribute to offering sufficient sites for grafting S–Ni species, constructing coupled heterostructure realize greatly improved kinetics both HER FOR processes. As result, S–Ni@Ni(OH)2/NF delivers an overpotential 50 mV at 10 mA cm–2 low potential 1.36 V acquire current density FOR. For HER||FOR-coupled system, built-in electrolyzer only needs 1.58 as well superior stability. This work presents facile strategy exploit bifunctional electrodes generation energy-saving way reforming.

Semiconductor-based photocatalytic reactions are a practical class of advanced oxidation processes (AOPs) to address energy scarcity and environmental pollution. By utilizing solar as clean, abundant, renewable source, this process offers numerous advantages, including high efficiency, eco-friendliness, low cost. In review, we present several methods construct various photocatalyst systems with excellent visible light absorption efficient charge carrier separation ability through the optimization materials design reaction conditions. Then it introduces fundamentals photocatalysis in both clean generation remediation. other parts, introduce approaches enhance activity by applying different strategies, semiconductor structure modification (e.g., morphology regulation, co-catalysts decoration, doping, defect engineering, surface sensitization, heterojunction construction) tuning optimizing conditions (such concentration, initial contaminant pH, temperature, intensity, charge-carrier scavengers). Then, comparative study on performance recently examined photocatalysts applied production remediation will be discussed. To realize these goals, H2 via water splitting, CO2 reduction value-added products, dye, drug photodegradation lessen toxic chemicals, presented. Subsequently, report dual-functional for simultaneous pollutant reactions. brief discussion about industrial economical applications is described. The follows introducing application artificial intelligence machine learning selection an innovative issues. Finally, summary future research directions toward developing significantly improved efficiency stability provided.

Abstract Photocatalytic degradation is one of the most promising methods for addressing environmental issues without introducing pollution sources. Nonetheless, majority works are devoted to explore high‐efficiency semiconductor photocatalysts, but potential risks in their application usually neglected. In this work, an environmentally friendly vesicle‐structured photocatalyst rationally designed by employing magnetic layered double oxide‐hollow spheres@antimony tin oxide as a core, phospholipid membrane, and carbon nanotubes (CNTs) channels, yielding multi‐structural material with robust organic pollutants photocatalytic mineralization ability. Materials characterization, computational modeling, cytotoxicity tests suggest that under visible light irradiation, photogenerated charges can be rapidly generated transfer core composite, H 2 O effectively activated generate hydroxyl radical rapid degradation. The construction membranes embedded CNTs not only maintains photodegradation performance material, also restrains its risk. Such synthetic approach advances development bionic materials.
