“…5b), outperforming the state-of-the-art Pt/CkRuO 2 water-splitting cell, which needs a potential of 1.498 V to reach the current density of 10 mA cm À2 , which is superior to those in recently reported literature for overall water splitting electrocatalysts. [57][58][59] To further examine the long-term stability of the WCoSe/WCo 3 O 4 bifunctional catalyst toward water splitting, we performed the chronopotentiometric test for our WCoSe/ WCo 3 O 4 kWCoSe/WCo 3 O 4 electrolyzer at a high current density of 100 mA cm À2 . As shown in Fig.…”

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.

“…In case of transition metal nitrides (TMNs), the d-band centers and densities of states (DOS) of the d orbitals enable noble-metallike behavior [98][99][100] in electrocatalysis and ensure good adsorption of reactants at the surfaces of TMNs. [101][102][103] Wang et al [104] used a 3D hollow structure of platinum-like vanadium nitride (VN) nanospheres as a highly efficient selective electrooxidation catalyst for HMF oxidation. The 3D VN was synthesized via a two-step process, as shown in Figure 5a.…”
