Infrared　(IR)　light　photo-thermocatalysis　has　been　motivated　by　the　realization　of　prospects　that　sunlight　is　an　inexhaustible　energy　source　where　infrared　photons　most　strongly　emitted　in　the　solar　spectrum　are　converted　into　thermal　energy,　which　thus　can　drive　different　redox　catalysis　applications,　e.g.,　oxidative　degradation　of　volatile　organic　compounds　(VOCs).　Herein,　we　report　that　the　hybrid　nanomaterial　Pt-rGO-TiO2,　featuring　the　broad　light　wavelength　absorption　(800-2500　nm),　can　be　used　as　a　highly　active　photo-thermal　responsive　catalyst　for　efficient　VOCs　decomposition　under　IR　irradiation.　The　maximum　photo-thermal　conversion　efficiency　is　able　to　reach　14.1%　with　a　significant　toluene　conversion　of　95%　and　CO2　yield　of　72%　under　infrared　irradiation　intensity　of　116　mW/cm(2),　along　with　retaining　its　stability　for　nearly　50　h.　The　comparison　characterizations　evidence　that　such　excellent　performance　is　predominantly　attributed　to　the　synergistic　effects　of　efficient　light-to-heat　conversion,　increased　adsorption　capacity　and　well　dispersed　supported　Pt-TiO2　catalyst　on　the　2D　rGO　sheet.　This　work　highlights　that　graphene-based　composites　as　IR　light　photon　absorber　show　great　promise　for　redox　reactions　through　photo-thermal　effect,　which　provides　an　alternative　and　feasible　strategy　for　solar　energy　conversion.
