“…Cobalt‐based nitride is also a type of promising co‐catalyst which is a noble metal substitute for photocatalytic applications. [ 169 ] Chen et al. reported that Co 3 N can be synthesized and used as a cocatalyst for enhanced photocatalytic H 2 production (≈137.33 mmol g –1 h –1 ) and apparent quantum yield (≈14.9% at 450 nm) in water based on CdS nanorods.…”

“…The photo‐generated electrons can be efficiently excited from the CB of the semiconductor to the surface of Co 3 N, thereby effectively separating the photoexcited hole pairs ( Figure a). [ 169 ] In addition, Co 3 N and semiconductor photocatalyst have tightly combined to form a tight metal‐semiconductor interface, thus also improving the electron transport efficiency. Thus, we can conclude that Co 3 N could collect and transport electrons to extend the carrier lifetimes and improve photocatalytic activity.…”

Photocatalysis is a promising and convenient strategy to convert solar energy into chemical energy for various fields. However, photocatalysis still suffers from low solar energy conversion efficiency. Developing state of the art photocatalysts with high efficiency and low cost is a huge challenge. Transition metal nitrides (TMNs) as a class of metallic interstitial compounds have attracted significant attention in photocatalytic applications. In fact, TMNs exhibit multifunctional properties in various photocatalytic systems. This review is the first attempt that summarizes recent research on TMNs‐based materials in various photocatalytic applications. Different roles of TMNs materials in photocatalytic systems including semiconductor active components, co‐catalysts, inter‐band excitation, and surface plasmon resonance components are systematically discussed and summarized. The fundamentals, latest progress, and emerging opportunities for further improving the performances of TMNs‐based materials for photocatalysis are also discussed. Finally, some challenges facing TMNs, and perspectives on their future that are relevant for furthering research in the area of photocatalysis are also proposed.

The facet‐engineered surface and interface design has attracted much attention in the preparation of efficient photocatalysts. Polyvinylpyrrolidone (PVP) is used as the morphological modifier to prepare 3D MoSx in this work. Benefit by its suitable conduction band position and good conductivity, CoN accepts photo‐induced electrons from MoSx as an excellent electron acceptor in the form of active sites. With the addition of CoN, hydrogen evolution performance of MoSx has been greatly improved by building the Mo−N bond since the form of Mo−N bond successfully shorten electron transport routes. The reason for the improved hydrogen precipitation efficiency is demonstrated by PL, XPS, and electrochemical characterization. The H2 production activity of MoSx@CoN with the best mass ratio of MoSx to CoN is up to 7617.5 μmol/g/h, and the hydrogen production stability of MoSx@CoN is also considerable. These findings provide new insights for the preparation of highly efficient photocatalytic hydrogen evolution materials.

Transition‐Metal‐Based Cocatalysts for Photocatalytic Water Splitting

View full text Add to dashboard Cite

Recently, semiconductor‐based photocatalytic water splitting has been extensively studied as a promising strategy for converting solar energy into carbon‐neutral and clean H2 fuel. However, the lack of sufficient active sites for surface redox reactions generally results in unsatisfactory photocatalytic water splitting performances over semiconductors. For this problem, cocatalyst provides an encouraging solution and is of great significance in improving photocatalytic performance. Noble metals and their derivatives are mostly utilized as efficient cocatalytic components, but their scarcity and expensiveness severely hamper large‐scale applications. Thereby, the utilization of noble‐metal‐free cocatalysts has aroused immense research attention. Owing to the facile availability, low cost, large abundance, high stability, and efficient performance, transition‐metal‐based materials have been developed as desirable candidates in the photocatalytic water splitting water splitting process. This review gives an outline of some recent advances in the active transition‐metal‐based water splitting cocatalysts. First, the fundamentals of transition‐metal‐based cocatalysts are presented, including the classification, function mechanisms, loading methods, modification strategies, and design considerations. Second, the various cases of depositing reduction cocatalysts, oxidation cocatalysts, and reduction–oxidation dual cocatalysts for water splitting are further discussed. Finally, the crucial challenges and possible research directions of transition‐metal‐based cocatalysts for photocatalytic water splitting are proposed.
