LaCoO3 is a perovskite-structured ceramic oxide compound combining lanthanum and cobalt, characterized by mixed valence cobalt cations that enable electronic and ionic conductivity. This material is primarily investigated for electrochemical applications where its catalytic activity and oxygen-deficient structure provide advantages in energy conversion and chemical sensing, with notable use in solid oxide fuel cells (SOFCs), oxygen permeation membranes, and catalytic converters where thermal stability and redox cycling tolerance are critical.
