2D Transition Metal Dichalcogenides‐Based Electrocatalysts for Hydrogen Evolution Reaction

Hydrogen is an efficient, clean, and economical energy source, owing to its huge density. Electrochemical water splitting a potential candidate for inexpensive eco-friendly hydrogen production. Recently, the development of 2D transition metal chalcogenides (TMDs) nanomaterials with variety physicochemical properties has shown their as eminent non-noble metal-based nanoscale electrocatalysts evolution. Nanostructuring such materials induces deep modification functionalities, compared bulk counterparts. High density different types exposed active sites formed, small diffusion paths, which enhances electron transfer in structures, can successfully aid charge collection process electrocatalytic evolution reactions. In this review, key parameters improve catalyst performance TMDs electrochemical reaction (HER) processes are discussed detail most recent developments field summarized, focusing on improvement activity TMDs. This review delivers insight clear understanding HER, suggesting new type efficient HER well other renewable fields.
