As the first crucial stage of development of hydrogen advanced technologies, as well as economic growth, the HER (hydrogen evolution reaction) has inevitably attracted considerable interest. Nevertheless, noble metals have traditionally been utilized as the electrocatalyst for HER, which has limited the potential of hydrogen technology to develop a large-scale and widely dispersed energy source. However, overpotential near to zero with a Tafel slope of 30 mV dec -1 can be achieved with Pt, although practical advancements to address the growing requirements for cheaper electrocatalysts are anticipated. Alloys, transition metal complexes, and even carbonaceous nanomaterials are all being evaluated as non-noble metal electrocatalysts. Among these, transition metal complexes (MX) appear to be the most practicable alternative, based on their electrocatalytic activity and electrochemical stability. This has prompted research toward cost-effective HER performance. Recently, transition metals-based compounds have been identified as promising contenders for stimulating hydrogen evolution owing to their low cost and engineering adaptability. Moreover, comparable to global Pt references, this material category has exhibited excellent HER performance with low overpotential, Tafel slopes, and good electrocatalytic stability. This chapter covers numerous key aspects and strategies for advancing transition metals-based compounds for HER applications. Additionally, an overview of the most prominent and remarkable developments in the chemical content along with interface structural properties of transition metal compounds, as well as their practical utilization in existing and prospective energy technologies, is presented herein.
