Abstract：

The　pure　silicon　MWW　were　synthesized　for　the　first　time　by　means　of　a　dry-gel　conversion　method　utilizing　N,　N,　N-trimethyl-1-adamantyl　ammonium　hydroxide　and　hexamethyleneimine　as　the　structural　directing　agents.　A　vapor　transport　assisted　crystallization　method　for　obtaining　complete　crystallinity　was　developed　to　replace　the　traditional　dry-gel　conversion　methods.　TiCl4　acid　solution　treatment　was　cleverly　used　for　the　implantation　of　titanium　in　MWW.　Compared　with　Ti-ERB-1,　the　Ti　content　of　boron-free　Ti-MWW　is　only　20%　of　the　former,　the　conversion　rate　of　1-hexene　epoxidation　is　2.3　times　of　the　former　and　nearly　100%　of　H2O2　efficiency.
