摘要

在金属-空气电池系统中,开发具有特殊氧还原反应活性的非贵金属催化剂是空气阴极的关键。本研究通过共掺杂策略,揭示了溶胶-凝胶工程合成La0.9Ce0.1Co0.1Mn0.9O3钙钛矿,并有针对性地探索了其在锌-空气和镁-空气电池体系中的电化学行为和潜在机制。钙钛矿La0.9Ce0.1Co0.1Mn0.9O3具有丰富的催化活性ORR位点和介孔结构。La0.9Ce0.1Co0.1Mn0.9O3的限扩散电流密度比商用Pt/C提高了1.2倍,H2O2产率低至0.27%,强调了其优越的质量传递动力学。la0.9 ce0.1 co0.1 mn0.9 o3基一次/二次锌空气电池的最大功率密度分别为130和83 mW cm−2,与Pt/C基锌空气电池相当。而以10 wt% KCl为电解液制备的镁空气电池的开路电压和最大功率密度分别为1.85 V和52 mW cm−2,表现出优于Pt/C催化剂的优点。结合DFT分析,La0.9Ce0.1Co0.1Mn0.9O3钙钛矿成为实现金属-空气电池的潜在ORR催化剂。

Ce, Co co-doped LaMnO3 perovskite activating oxygen reduction reaction in Zn-air and Mg-air batteries

Ce, Co co-doped LaMnO3 perovskite activating oxygen reduction reaction in Zn-air and Mg-air batteries
Within the domain of metal-air battery systems, developing the non - precious metal catalysts featuring extraordinary catalytic activity in oxygen reduction reaction (ORR) is crucial to the air-cathode. This work unveils a sol-gel engineered synthesis of La0.9Ce0.1Co0.1Mn0.9O3 perovskite via the co-doping strategy, with targeted exploration of its electrochemical behavior and underlying mechanism in Zn-air and Mg-air battery systems. The perovskite La0.9Ce0.1Co0.1Mn0.9O3 has a wealth of catalytically active ORR sites and a mesoporous architecture. The diffusion-limited current density of La0.9Ce0.1Co0.1Mn0.9O3 successfully achieves a 1.2-fold enhancement relative to commercial Pt/C with a low H2O2 yield of <0.27 %, underscoring its superior mass transport kinetics. The maximum power densities of La0.9Ce0.1Co0.1Mn0.9O3-based primary/secondary zinc - air batteries are 130 and 83 mW cm−2, respectively, which are on a par with those of Pt/C - based Zinc - air batteries. Whereas, the open - circuit voltage and maximum power density of the primary magnesium - air battery fabricated with 10 wt% KCl as the electrolyte are 1.85 V and 52 mW cm−2, respectively, which exhibit superiority over Pt/C catalysts. In combination with DFT analyses, the La0.9Ce0.1Co0.1Mn0.9O3 perovskite emerges as a prospective ORR catalyst for metal-air battery realization.
