“…fabricated the ternary nitride Cr 0.5 Ti 0.5 N NPs with CdS semiconductor as the base. [ 22 ] They attained the best photocatalytic H 2 production rate of 2.44 mmol g –1 h –1 , which is ≈120 times higher than that of pure CdS sample and even higher than that of Pt‐based nanocomposites (2.06 mmol g –1 h –1 ) (Figure 8c). Thus, it is proved that CrTi ternary nitride has much better photocatalytic efficiency than those of the binary nitride of Cr and Ti.…”

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.

“…Among these catalytic materials, MNs have evolved extremely promising owing to their exquisite characteristic features such as high electrical conductivity, high structural stability under extreme thermal conditions, and corrosion resistance [ 32 ]. For example, MNs of molybdenum [ 33 ] and titanium [ 34 ] have widely been reported for their high efficiency for hydrogen production. MNs, in general, possess high electron density, thermal and chemical stability, structural stability and adjustable band gap which are favorable factors for hydrogen production through either electrochemical or photocatalytic pathways.…”

The over-dependence on fossil fuels is one of the critical issues to be addressed for combating greenhouse gas emissions. Hydrogen, one of the promising alternatives to fossil fuels, is renewable, carbon-free, and non-polluting gas. The complete utilization of hydrogen in every sector ranging from small to large scale could hugely benefit in mitigating climate change. One of the key aspects of the hydrogen sector is its production via cost-effective and safe ways. Electrolysis and photocatalysis are well-known processes for hydrogen production and their efficiency relies on electrocatalysts, which are generally noble metals. The usage of noble metals as catalysts makes these processes costly and their scarcity is also a limiting factor. Metal nitrides and their porous counterparts have drawn considerable attention from researchers due to their good promise for hydrogen production. Their properties such as active metal centres, nitrogen functionalities, and porous features such as surface area, pore-volume, and tunable pore size could play an important role in electrochemical and photocatalytic hydrogen production. This review focuses on the recent developments in metal nitrides from their synthesis methods point of view. Much attention is given to the emergence of new synthesis techniques, methods, and processes of synthesizing the metal nitride nanostructures. The applications of electrochemical and photocatalytic hydrogen production are summarized. Overall, this review will provide useful information to researchers working in the field of metal nitrides and their application for hydrogen production.
