Pt/CeO2-Co3O4　catalyst　(Pt/CeCo)　was　prepared　by　anchoring　Pt　species　on　the　CeO2-Co3O4　support　that　derived　from　metal-organic　framework　precursor.　The　Pt/CeCo　catalyst　exhibited　an　eminent　toluene　catalytic　activity　compared　with　Pt/Co3O4.　The　improvement　of　catalytic　performance　for　Pt/CeCo　catalyst　was　attributed　to　surface　Co3+　sites　and　Pt0　species　by　the　enhanced　SMSI,　where　Co3+　sites　were　benefical　for　the　toluene　activation　and　Pt0　species　were　conducive　to　oxygen　activation.　Moreover,　the　high　mobility　of　surface　active　oxygen,　excellent　low-temperature　reducibility　and　plentiful　oxygen　vacancies　further　ensured　the　exceptional　catalytic　performance.　The　in　situ　DRIFTS　demonstrated　that　the　ring-opening　of　benzoic　acid　into　maleic　anhydride　was　the　rate-determining　step　and　that　the　Pt/CeCo　catalyst　underwent　an　accelerated　toluene　oxidation　process　compared　with　Pt/Co3O4　catalyst.
