Опубликована: Ноя. 1, 2023

Transition metal oxides are promising electrocatalysts for zinc-air batteries, yet surface reconstruction caused by the adsorbate evolution mechanism, which induces zinc-ion battery behavior in oxygen reaction, leads to poor cycling performance. In this study, we propose a lattice mechanism involving proton acceptors overcome performance of OER process. We introduce stable solid base, hydroxy BaCaSiO4, onto surfaces PrBa0.5Ca0.5Co2O5+δ perovskite nanofibers with one-step exsolution strategy. The HO-Si sites on BaCaSiO4 significantly accelerate transfer from OH* adsorbed during As proof concept, rechargeable assembled composite electrocatalyst is an alkaline environment over 150 hours at 5 mA cm-2 galvanostatic charge/discharge tests.

DFT calculation was further applied explore reaction mechanism. We found that atoms serve as reduction evolution catalytic respectively facilitate adsorption OH* desorption. More importantly, co-adsorption OOH* on Mn/Ru dual can greatly enhance activity. The resulting Mn-RuO2 catalyst exhibits an ultra-low ORR/OER overpotential just 0.65 V, substantially lower than RuO2 MnOx. Remarkably, also demonstrates excellent stability, with minimal ORR decay after repeated OER cycling.
