“…This newly designed bimetallic selenide incorporated efficient morphology that enhanced its catalytic performance but still depends on long‐term, cost‐efficient, and expensive techniques to improve the vitality and potency of energy dynamics. Thus, Zhou et al [ 58 ] adopted a simple two‐step (hydrothermal and carbonization) method for the synthesis of Mo‐doped cobalt selenide fabricated on carbon nanospheres (NC). The uniform porous NC was formed via carbonization at 900 °C in an argon atmosphere for 6 h at a temperature rate of 5C min −1 .…”

Novel catalytic materials are under investigation to find convincing energy alternatives. In this context, transition metal selenides (TMSes) are found to be feasible, ecofriendly, and effective electrocatalysts with futuristic characteristics. A deep and comprehensive investigation on metal selenides for energy conversion and storage application is summarized in this review article. Different methods such as hydrothermal, solvothermal, coprecipitation, hot injection, successive ionic layer adsorption reaction, polyol, and others can be used for the synthesis of metal selenides based electrocatalysts, with different morphologies and compositions. The morphology of metal selenides is strongly controlled by factors such as reaction time, temperature, pH of the reaction medium, and surfactant. The electrochemical applications of metal selenides are governed by morphology, active spots for reaction, surface engineering, and confinement. It is concluded that TMSes deliver high performance with large surface area, which is possible due to their porous or 3D morphology. The TMSes with multimetal or with doping metal/nonmetals perform better compared to single atoms. It is concluded that the reaction mechanism of hydrogen evolution reaction and oxygen evolution reaction is a primary tool to better understand the system to develop more efficient catalysts for practical application.

Developing excellent electrocatalysts to replace noble metal catalysts and improve hydrogen production via water splitting is a daunting task. Bimetallic transition metal phosphides (TMPs) display improved performance than monometallic transition metal phosphides due to their synergistic effects. Moreover, research has proven that supporting them on conductive substrates can further enhance their electrochemical performance. Recently, metal‐organic frameworks (MOFs) are incorporated into bimetallic TMPs for enhanced performance. This review starts with a synopsis of the reaction mechanisms and performance parameters of hydrogen evolution reaction (HER) electrocatalysts. Moreover, the strategies for enhancing the performance of bimetallic TMPs and improving the hydrophilicity of TMPs are also discussed. In conclusion, the challenges and perspectives of bimetallic transition metal phosphides are discussed. This review analyses the extensive progress in this research domain and proffers insights that can aptly guide the future development of more excellent TMPs and other transition metal electrocatalysts for enhanced hydrogen evolution reaction.
