Propylene　is　the　second　most　important　chemicals　in　the　petrochemical　industry.　Propane　dehydrogenation　as　the　on-purpose　propylene　production　route,　has　attracted　much　attentions　due　to　great　success　in　the　exploitation　of　shale　gas.　Recently,　Pt@zeolite　is　proven　to　the　most　promising　catalyst　for　propane　dehydrogenation,　because　Pt　clusters　encapsulated　in　zeolite　channel　show　high　resistance　to　Pt　particles　sintering.　However,　the　micropore　of　zeolite　imposes　severe　diffusion　limitation　of　propylene,　and　thus　the　coke　formation　easily　takes　place　which　leads　to　a　fast　deactivation.　Herein,　we　report　efficient　Pt/Zn-MFIhierarchical　catalysts　for　PDH　with　auxiliary　mesopore　for　accelerating　mass　transfer,　and　these　Pt/Zn-MFIhierarchical　exhibit　not　only　high　thermal　stability　but　also　excellent　resistance　to　coking.　The　Pt/Zn-MFIhierarchical　catalyst　is　obtained　by　an　introduction　of　Pt　species　into　the　hierarchically　porous　Zn-MFI　that　is　prepared　from　one-step　hydrothermal　synthesis.　The　formed　Pt-Zn　clusters　are　exclusively　located　in　the　micropore　of　MFIhierarchical,　and　the　migrating　of　Pt-Zn　clusters　is　largely　prevented　under　the　harsh　reaction　conditions.　Mesopores　in　MFIhierarchical　greatly　enhances　the　diffusion　rate　of　propylene,　which　significantly　alleviates　the　coke　formation　arising　from　polymerization　of　propylene.　The　most　efficient　Pt/Zn-MFI-120hierarchical　catalyst　delivers　propane　conversion　of　around　46　%　and　propylene　selectivity　of　above　98　%.　This　catalyst　undergoes　a　slow　loss　of　activity　with　a　deactivation　rate　kd　of　as　low　as　0.005　h−1,　and　its　catalytic　performance　can　be　fully　restored　via　a　simple　calcination.　©　2024　Elsevier　B.V.
