Nano-Sized Double Perovskite Oxide as Bifunctional Oxygen Electrocatalysts

Abstract

Double perovskite oxide La2Co0.5Fe0.5MnO6-d is synthesized by the moltensalt- assisted method with Nano-sized particles (≈55 nm). The as-obtained La2Co0.5Fe0.5MnO6-d exhibits obviously enhanced electro catalytic activities towards oxygen evolution reaction and oxygen reduction reaction compared to the counterpart La2CoMnO6-d. This work provides a simple method to synthesize Nano-sized double perovskite oxide as superior electro catalysts for energy conversion.
