Abstract：

In　this　work,　a　series　of　x　wt%　Pt@TiO2　(x　=　0.18,　0.42,　and　0.84)　catalysts　with　highly　dispersed　Pt　nanoparticles　(NPs)　are　synthesized　via　pyrolysis　method　using　Ti-based　metal-organic　frameworks　(MOFs)　as　precursors.　Physicochemical　properties　of　the　catalysts　are　characterized　by　a　number　of　analytical　techniques.　It　is　shown　that　all　samples　possess　mesoporous　structure　with　surface　area　of　59–75.6　m2/g,　thus　can　suppress　the　aggregation　of　Pt　NPs,　and　enhance　toluene　adsorption　and　diffusion.　The　0.84　wt%　Pt@TiO2　catalyst　exhibits　the　best　catalytic　performance　for　toluene　oxidation　(T90%　=150　°C　at　space　velocity　=　20,000　mL/　(g　h)),　which　is　attributed　to　the　higher　surface　area,　abundant　adsorbed　oxygen　and　Pt0　species,　and　strong　interaction　between　Pt　NPs　and　TiO2.　In　addition,　the　possible　reaction　mechanism　of　toluene　oxidation　is　proposed　based　on　in　situ　DRIFTS　technique.　©　2024　Elsevier　B.V.
