Rapid industrial growth has overexploited fossil fuels, making hydrogen energy a crucial research area for its high and zero carbon emissions. Water electrolysis is promising method as it greenhouse gas-free energy-efficient. However, OER, slow multi-electron transfer process, the limiting step. Thus, developing efficient, low-cost, abundant electrocatalysts vital large-scale water electrolysis. In this paper, application progress of transition metal chalcogenides (TMCs) catalysts oxygen evolution reaction in recent years are comprehensively reviewed. The key findings highlight catalytic mechanism performance TMCs synthesized using single or multiple metals. Notably, modifications through recombination, heterogeneous interface engineering, vacancy, atom doping found to effectively regulate electronic structure chalcogenides, increasing number active centers reducing adsorption intermediates barriers OER. paper further discusses shortcomings challenges OER catalysts, including low electrical conductivity, limited sites, insufficient stability under harsh conditions. Finally, potential directions new TMC with enhanced efficiency proposed.
