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.

The oxygen evolution reaction (OER) is a pivotal process in numerous renewable energy conversion technologies. However, its sluggish intrinsic kinetics and intricate transfer impede the efficient of energy. Activating lattice mechanism (LOM) paramount importance to break through theoretical scaling relationship boost catalytic activity. In this contribution, N F are successfully introduced into Co3O4 simultaneously as heteroatoms via controllable plasma strategy modulate covalency property metal-oxygen. Theoretical simulations experiment results demonstrated that cobalt-oxygen bond significantly enhanced under synergistic effect F, triggering LOM pathway facilitating OER process. N, F-Co3O4 composite displays an impressive performance, exhibiting low overpotential 254 mV at 10 mA cm-2 remarkable stability 20, 150, 400 cm-2. addition, also exhibits 285 20 1 m KOH + 0.5 NaCl solution, performance on overall water splitting. This work offers profound insights crucial for enhancing electrocatalytic activity spinel oxides.
