Light-driven　photothermocatalytic　oxidation　is　a　promising　method　for　the　elimination　of　volatile　organic　compounds　(VOCs).　The　Co3O4,　0.46　Pt/Co3O4　and　0.97　Pt/Co3O4　catalysts　were　fabricated　via　the　simple　molten　salt　and　incipient　wetness　impregnation　method.　Compared　with　Co3O4　and　0.46　Pt/Co3O4,　the　0.97　Pt/Co3O4　catalyst　showed　higher　photothermocatalytic　performance　for　toluene　oxidation　under　simulated　solar　irradiation　intensity　of　900　mW　cm-2,　with　the　toluene　conversion　and　CO2　yield　being　up　to　98.3　%　and　96.0　%,　respectively.　The　better　activity　was　ascribed　to　its　outstanding　strong　light　absorption　and　low　temperature　reducibility.　Meanwhile,　0.97　Pt/Co3O4　also　exhibited　an　excellent　photothermocatalytic　stability　and　H2O　resistance.　The　Vis-IR　light　played　a　key　role　in　the　photothermocatalytic　oxidation　of　toluene　in　the　whole　solar　spectrum.　This　work　benefited　the　synthesis　of　catalysts　with　good　photothermocatalytic　activity　for　environment　friendly　treatment　of　VOCs.
