Perovslcite-type　oxides,　due　to　their　structural　stability　and　special　physical　and　chemical　properties,　have　become　important　topics　in　the　field　of　catalytic　materials　research.　This　article　focuses　on　the　effect　of　gamma-ray　irradiation　on　the　catalytic　activity　of　LaCoO3　and　BaPbO3.　X-ray　diffraction　(XRD),　X-ray　photoelectron　spectroscopy　(XPS)　and　temperature-programmed　reduction　(TPR)　were　used　to　analyze　the　physical　and　chemical　properties　of　LaCoO3　and　BaPbO3.　Finally,　H2O2　catalytic　decomposition　and　toluene　catalytic　combustion　experiments　were　performed　to　verify　the　activity　of　LaCoO3　and　BaPbO3　before　and　after　irradiation.　The　results　show　that　after　gamma-ray　irradiation,　the　activity　of　LaCoO3　and　BaPbO3　on　catalytic　hydrogen　peroxide　decomposition　was　reduced,　and　the　activity　of　catalytic　toluene　combustion　was　enhanced.
