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 slow kinetics of the oxygen evolution reaction limits electrochemical overall water splitting (OWS). To address this, integrating thermodynamically favorable organic electro-oxidation with hydrogen (HER) can enhance production performance. Notably, 5-amino-1H-tetrazole oxidation-assisted OWS not only achieves energy-saving but also produces energetic compound 5,5'-azotetrazolate salts in a mild manner. This necessitates in-depth research into catalysts straightforward synthesis methods and excellent performance for production. Supported single-atom (SACs) have high dispersibility reduce use precious metals. Here, we report highly efficient HER catalyst consisting Ru single atom anchored on low-crystallinity Zn-doped Ni2P nanosheets (Ru-LC-ZNP). low overpotential 28.9 mV at -10 mA cm-2, demonstrating stability least 100 h no noticeable activity loss. experimental results indicate that outstanding alkaline be attributed to synergistic optimization between support. By coupling 5-AT electro-oxidation, cell voltage electrolysis enormously reduced 1.26 V 10 cm-2. work provides insights mechanism supported SACs as active catalysts.
