Abstract：

Platinum　nanoparticles　(Pt　NPs)　embedded　in　the　multi-hollow　silicalite-1　zeolite　(Pt@MH-S-1)　were　prepared　by　the　sequential　alkali　etching　and　recrystallization　of　parent　microporous　silicalite-1　zeolite.　Then,　toluene　and　acetone　were　employed　as　probe　molecules　to　determine　the　catalytic　behavior　of　Pt@MH-S-1　for　the　elimination　of　volatile　organic　compounds　(VOCs).　The　results　reveal　that　Pt@MH-S-1　with　multi-hollow　structure　owns　large　external　specific　surface　area　for　dispersing　the　Pt　NPs,　and　abundant　mesoporous　channels　for　improving　the　accessibility　of　toluene　to　Pt　NPs　as　well　as　high　reactive　oxygen　content,　excellent　toluene　adsorption　capacity　and　moderate　adsorption　strength.　Owing　to　these　characteristics,　Pt@MH-S-1　exhibits　superior　performance　both　in　toluene　and　acetone　catalytic　oxidations　as　reflected　by　100%　conversion　acquired　at　even　a　low　temperature　of　137　and　180　°C,　respectively.　Moreover,　Pt@MH-S-1　also　shows　good　stability　toward　the　various　conditions,　signifying　its　superiority　and　potential　in　practical　application　for　VOCs　treatment.　©　2023　Elsevier　Ltd
