2D Transition Metal Dichalcogenides for Efficient Hydrogen Generation

The transition towards renewable energy sources is imperative as conventional fossil fuels are being depleted and have harmful impact on the environment and human life. Hydrogen (H2) has become a favorable energy carrier because of its significant energy density. Green production methods such as electrochemical water splitting shows promise as a low cost and environmentally benign approach for H2 generation. Lately, the progress in 2D transition metal chalcogenides (TMDs) nanomaterials with diverse physicochemical features has demonstrated their promise as prominent non-noble metal-based electrocatalysts for hydrogen evolution reaction (HER). This review explores recent advancements in TMD-based electrocatalysts for HER, highlighting the mechanisms of HER, parameters for evaluation of electrochemical water splitting, strategies for enhancing performance, and future research directions. Through a comprehensive examination of recent literature, this review provides insights into the potential of TMDs in advancing renewable energy technologies and the development of highly efficient catalyst towards HER.
