Perovskite oxides are promising electrocatalysts due to their rich composition, facile synthesis, and favorable stability under oxidizing conditions. Despite extensive research on doping strategies, the impact of cation nonstoichiometry electrocatalytic performance is less understood. Here, we reveal that A-site significantly influences phase evolution Bax(Co, Fe, Zr, Y)O3−δ, transitioning from a single cubic perovskite (x = 1) nanocomposite comprising major minor hexagonal swedenborgite (0.80 ≤ x 0.95). The with nominal chemical composition Ba0.80Co0.7Fe0.1Zr0.1Y0.1O3−δ showed markedly enhanced for oxygen reaction (OER) in alkaline solutions synergistic effect two strongly interacting phases, promoting lattice-oxygen-participating OER pathway. Further optimizing allowed design nanocomposites controlled concentrations. optimal candidate, an increased content phase, demonstrated further boosted performance.

Proton Exchange Membrane Water Electrolysis (PEMWE) under acidic conditions outperforms alkaline water electrolysis in terms of less resistance loss, higher current density, and produced hydrogen purity, which make it more economical long-term applications. However, the efficiency PEMWE is severely limited by slow kinetics anodic oxygen evolution reaction (OER), poor catalyst stability, high cost. Therefore, researchers past decade have made great efforts to explore cheap, efficient, stable electrode materials. Among them, RuO2 electrocatalyst has been proved be a major promising alternative Ir-based catalysts most OER owing its excellent electrocatalytic activity pH adaptability. In this review, we elaborate two mechanisms (lattice mechanism adsorbate mechanism), comprehensively summarize discuss recently reported RuO2-based electrocatalysts conditions, propose many advanced modification strategies further improve stability OER. Finally, provide suggestions for overcoming challenges faced practical applications prospects future research. This review provides perspectives guidance rational design highly active based on PEMWE.
