The electrochemical oxygen reduction reaction (ORR) is pivotal in energy conversion via a 4e⁻ ORR pathway and green hydrogen peroxide production 2e⁻ pathway. Transition metal single atom catalysts (TM SACs) have attracted intense attention recent years for due to their high activity near maximum utilization. future development of TM SACs requires improved understanding pathways, since currently the true origin remains contentious owing lack qualitative/quantitative information about active sites. Knowledge-guided design imperative optimization performance terms selectivity. This review focuses on latest progress ORR, placing particular efforts elucidate mechanisms. Experimental evidence based in-situ/operando characterization measurements, along with theoretical predictions, are summarized deepen structure-performance relationships at both atomic molecular level. Finally, some perspectives offered relating fundamental science needed find practical application storage devices. We hope this will inspire new synthetic routes towards high-performance electrocatalysts sector.

To meet the demanding requirements for clean energy production, need to develop advanced electrocatalysts efficiently catalysing water splitting reactions attracts a continuously increased attention. However, anticipated expansion in green hydrogen production from renewable sources, catalysts used reaction not only satisfy required figures of merit but should concurrently be based mainly on abundant, non-critical materials with low environmental impact. In last decades, non-noble metal catalysts, transition metals, rare-earth dichalcogenides, and light elements such as phosphorus, nitrogen, sulphur have shown improved performance. Moreover, recent years interest has been focused variations materials, more specifically introduction defects further boost their catalytic Through many studies performed over years, it is now possible summarize, understand describe role these reactions, namely oxygen evolution thereby suggest strategies development next generation electrocatalysts. This goal current review; we critically summarize latest progress introduced electrolysis applications by scrutinizing structure–performance correlation well specific activity. A broad class nanomaterials covered, comprising oxides carbides, carbon-based metal–organic frameworks (MOFs). Finally, main challenges future perspectives this rapidly evolving field are provided at end review.
