Abstract:　Diffusion　limitation　caused　by　microporous　molecular　sieves　has　always　been　a　bottleneck　problem　in　liquid　phase　epoxidation.　In　this　study,　several　different　carbon　sources　were　used　as　hard　templates　to　prepare　hierarchically　porous　zeolite　Ti-MWW　(cTi-MWW)　successfully.　Compared　with　conventional　Ti-MWW,　cTi-MWW　has　an　additional　hierarchically　porous　structure　and　abundant　pore　structure　distribution.　Especially,　the　cTi-MWW　prepared　with　polyethylene　glycol1540　(PEG)　as　the　hard　template　not　only　has　a　multiple　hierarchically　porous　structure,　but　also　exhibits　small　crystal　size　and　good　hydrophobicity　properties　studied　by　TEM　and　in　situ　FT-IR.　At　the　same　time,　the　cTi-MWW　prepared　with　PEG　exhibits　better　activity　than　the　conventional　Ti-MWW　in　the　selective　epoxidation　reaction　of　allyl　alcohol　(AAL)　with　H2O2　as　oxidant　and　the　conversion　is　improved　by　11%　(Si/Ti　=　20).　And　a　higher　efficiency　and　longer　catalyst　life　in　fixed-bed　catalytic　reactor　were　exhibited　by　using　cTi-MWWPEG　as　catalyst.　The　physicochemical　properties　of　cTi-MWW　prepared　with　different　hard　templates　were　systematically　studied　by　SEM,　XPS,　UV–Vis,　XRD　and　N2　absorption–desorption　techniques.　This　method　is　effective　for　the　synthesis　of　cTi-MWW　and　significant　for　the　preparation　of　hierarchically　porous　zeolites　in　industrial　production.　Graphic　Abstract:　A　hierarchically　porous　zeolite　Ti-MWW　prepared　with　different　hard　templates　successfully.　With　the　hierarchically　porous　structure,　which　have　better　adsorption,　diffusion,　and　reactivity　in　liquid　phase　epoxidation,　thus　improving　the　catalytic　activity.　Especially,　the　hierarchically　porous　zeolite　Ti-MWW　prepared　with　polyethylene　glycol　exhibits　small　crystal　size　and　good　hydrophobicity　properties.[Figure　not　available:　see　fulltext.].　©　2019,　Springer　Science+Business　Media,　LLC,　part　of　Springer　Nature.
