Abstract Perovskite‐type LaCoO 3 was prepared by stearic acid solution combustion method and characterized by XRD, DSC‐TG, and XPS techniques. The catalytic activities of LaCoO 3 for HMX (octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine) thermal decomposition were investigated. The as‐prepared LaCoO 3 shows higher activity than the calcined one. This could be due to higher concentration of surface‐adsorbed oxygen and hydroxyl species as well as higher BET surface area of the as‐prepared LaCoO 3 .
