Industrial　flue　gas　has　a　great　impact　on　the　atmosphere　environment　and　human　health,　and　its　emission　temperatures　are　usually　below　180　°C,　which　needs　a　new　technology　that　can　catalyze　the　removal　of　the　multicomponent　VOCs　over　high-performance　catalysts　in　the　presence　of　ozone.　In　this　work,　we　prepared　the　Pt/CeO2　catalysts　with　different　morphologies　of　Pt　particles　and　investigated　their　catalytic　performance　for　the　ozonization　of　mixed　VOCs　(i.e.,　toluene　and　chlorobenzene　(CB)).　Among　all　of　the　as-prepared　samples,　Pt　NRs/CeO2　with　nanorod-like　Pt　particles　showed　excellent　catalytic　performance　for　the　ozonization　of　toluene　and　CB.　The　T50%　(the　temperature　at　VOC　conversion　=　50%)　values　for　toluene　and　CB　ozonization　were　40　and　48　°C　at　a　space　velocity　of　40,000　mL　g-1　h-1,　respectively.　The　results　of　characterization　revealed　that　the　reactive　oxygen　species　involved　in　the　VOC　ozonization　were　mainly　the　O2-　and　O22-　species,　surface　oxygen　vacancies　of　CeO2　were　the　active　sites　for　the　conversion　of　ozone　to　the　reactive　oxygen　species,　and　the　O2-　species　was　the　mainly　active　oxygen　species　in　the　low-temperature　VOC　oxidation.　Furthermore,　partial　reactive　oxygen　species　reacted　with　the　Ptn+　species　to　generate　more　amount　of　the　Pt0　species,　and　the　metallic　platinum　species　was　the　main　active　site　for　the　adsorption　and　activation　of　toluene　and　CB.　The　chemisorbed　VOCs　at　the　Pt0　sites　reacted　with　the　reactive　oxygen　species　at　the　interface　of　Pt　and　CeO2,　resulting　in　the　excellent　low-temperature　catalytic　activity.　Compared　with　the　reaction　without　ozone　participation,　we　find　that　the　participation　of　ozone　can　not　only　decrease　the　reaction　temperature　but　also　reduce　the　production　of　toxic　byproducts.　We　are　sure　that　the　Pt/CeO2　catalyst　is　promising　in　practical　application　for　elimination　of　the　VOCs　from　industrial　flue　gas.　©　2023　American　Chemical　Society
