Abstract：

Nanocarbon-supported　Pt　nanoparticles　(NPs)　were　prepared　and　tested　for　the　propane　dehydrogenation　reaction　(PDH).　The　nanocarbon　support　is　composed　of　a　nanodiamond　core　and　a　defective,　ultrathin　graphene　nanoshell　(ND@G).　The　Pt/ND@G　catalyst　experienced　slight　deactivation　during　the　100　h　PDH　test,　while　the　Pt/Al　2　O　3　catalyst　showed　severe　deactivation　after　the　20　h　PDH　test.　Pt　NPs　exhibited　superior　sintering　resistance　versus　that　of　the　ND@G　support.　This　particular　support　structure　of　ND@G　allows　electrons　on　the　defects　to　transfer　to　the　Pt　NPs,　leading　to　a　strong　metal-support　interaction,　which　significantly　prevents　Pt　NP　sintering　and　promotes　the　desorption　of　electron-rich　propylene.　This　electron　transfer　mechanism　was　also　confirmed　by　a　CO　catalytic　oxidation　test.　©　2017　American　Chemical　Society.
