The lattice oxygen mechanism (LOM) plays a critical role in the acidic evolution reaction (OER) as it provides more efficient catalytic pathway compared to conventional adsorption (AEM). LOM effectively lowers energy threshold of and accelerates rate by exciting atoms catalyst directly participate OER process. In recent years, with increase in-depth understanding LOM, researchers have developed variety iridium (Ir) ruthenium (Ru)-based catalysts, well non-precious metal oxide optimized their performance through different strategies. However, still faces many challenges practical applications, including long-term stability precise modulation active sites, application efficiency real electrolysis systems. Here, we review OER, analyze its difference traditional AEM new (OPM) mechanism, discuss experimental theoretical validation methods pathway, prospect future development electrocatalyst design conversion, aiming provide fresh perspectives strategies for solving current challenges.

Abstract The utilization of single atoms (SAs) as trifunctional electrocatalyst for nitrogen reduction, oxygen and evolution reactions (NRR, ORR, OER) is still a formidable challenge. Herein, we devise one‐pot synthesized palladium SAs stabilized on nitrogen‐doped carbon SA (Pd‐SA/NC) efficient NRR, OER. Pd‐SA/NC performs robust catalytic activity toward NRR with faradaic efficiency 22.5% at −0.25 V versus reversible hydrogen electrode (RHE), the relative Pd enhanced by 17‐fold than Pd‐NP/NC. In addition, half‐wave potential reaches 0.876 RHE, amounting to 58‐time higher mass commercial Pt/C. Moreover, overpotential 10 mA cm −2 low 287 mV Pd‐SA/NC, outperforming IrO 2 360 times in turnover frequency 1.6 RHE. Accordingly, assembled rechargeable zinc‐air battery (ZAB) achieves maximum power density 170 mW , boosted 2.3 Pt/C–IrO . Two constructed ZABs efficiently NRR‐OER system electrochemically generate ammonia implying its superior trifunctionality.
