In　this　research,　a　novel　green　mechanochemical　dry　gel　conversion　method　(MDGC)　is　reported　to　obtain　submicron-sized　Ti-rich　MWW　zeolite.　First,　titanium　and　silica　sources　were　milled　under　milder　conditions　in　a　planetary　ball　mill　to　construct　the　uniform　SiO2-TiO2　composite　powders　with　higher　Ti　contents.　Subsequently,　submicron-sized　Ti-rich　MWW　zeolite　powder　was　prepared　via　dry　gel　conversion　(DGC)　route　using　the　obtained　composite　under　mixed　steam　environment　consisting　of　water　and　piperidine.　The　physicochemical　properties　of　the　SiO2-TiO2　composites　before　and　after　calcination　and　corresponding　Ti-MWW-MDGC　were　investigated　by　XRD,　UV-Vis,　FT-IR,　SEM,　XRF,　and　N-2　absorption-desorption.　Moreover,　Ti-MWW　(30)-MDGC　exhibited　a　superior　catalytic　activity　during　epoxidation　with　H2O2　compared　with　the　traditional　DGC　method,　and　the　conversion　of　1-hexene　increased　from　4.2%　to　26.3%.　The　MDGC　method　is　a　promising　approach　for　the　green　production　of　various　zeolites　with　higher　heteroatom　contents,　such　as　TS-1,　Ti-Beta　and　Sn-MWW,　etc.　(C)　2020　The　Society　of　Powder　Technology　Japan.　Published　by　Elsevier　B.V.　and　The　Society　of　Powder　Technology　Japan.　All　rights　reserved.
