Special Issue Information

Dear Colleagues,

The unique properties of nanomaterials, such as surface effects, volume effects, and quantum size effects, have attracted much attention in the field of photo(electro)catalysis, which is one of the most promising advanced technologies in the area of catalysis and has laid the foundation for the design and construction of nanostructured catalysts. The design and construction of photo(electro)catalysts with nanostructures can effectively optimize the light absorption capacity, the photogenerated electron–hole separation efficiency, and the surface redox reaction rate. Therefore, finding how to controllably synthesize nanostructures for photo(electro)catalysis is crucial in the field of photo(electro)catalysis. Meanwhile, the characterization of nanostructured catalysts is pivotal to revealing the photo(electro)catalytic mechanism, thus guiding the design and construction of advanced nanocatalysts with excellent photo(electro)catalytic performance. Advanced characterization techniques are used to study the atomic and electronic structures of nanomaterials and track the evolution of the surface structure and adsorbed species of nanomaterials under operating conditions. Furthermore, nanomaterial applications in the fields of photo(electro)catalytic CO2 reduction, photo(electro)catalytic H2 production, and photo(electro)catalytic degradation have encountered many challenges. Therefore, this Special Issue will focus on the latest synthesis strategies, characterization techniques, and various applications of nanostructures for photo(electro)catalysis to reveal the photo(electro)catalytic mechanism and structure–activity relationships and facilitate better design and construction of advanced photo(electro)catalysts suitable for practical applications.

With the intensification of global resource shortages and the environmental crisis, hydrogen energy has garnered significant attention as a renewable and clean energy source. Water splitting is considered the most promising method of hydrogen production due to its non-polluting nature and high hydrogen concentration. However, the slow kinetics of the two key reactions, the Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER), have greatly limited the development of related technologies. Meanwhile, the scarcity and high cost of precious metal catalysts represented by Pt and Ir/RuO2 limit their large-scale commercial application. Thus, it is essential to develop catalysts based on Earth’s transition metals that have abundant reserves. Vanadium (V) is an early transition metal with a distinct electronic structure from late transition metals such as Fe, Co, and Ni, which has been emphasized and studied by researchers. Numerous vanadium-based electrocatalysts have been developed for the HER and OER. In this review, the mechanisms of the HER and OER are described. Then, the compositions, properties, and modification strategies of various vanadium-based electrocatalysts are summarized, which include vanadium-based oxides, hydroxides, dichalcogenides, phosphides, nitrides, carbides, and vanadate. Finally, potential challenges and future perspectives are presented based on the current status of V-based electrocatalysts for water splitting. Full article
