Abstract

It has become a challenge to further enhance the electrocatalytic performance of perovskite oxides due to their limited active surface area. Herein, we propose a top-down strategy for the amorphization of crystalline LaCoO3 nanopowders with significantly enhanced specific surface area and electrocatalytic oxygen evolution reaction (OER) activity and durability, in which the overpotential at the current density of 10 mA cm–2 reduced from 405 to 293 mV, and the Tafel slope decreased from 96.6 to 63.4 mV dec–1. This work provides an effective method for the property optimization of nanometer perovskite oxides and the design of high-performance electrocatalysts.
