Fabrication of oriented zeolite L monolayer via covalent molecular linkers

摘要

For the first time, 1,4-diisocyanatobutane (DICB) Was used as the covalent molecular linker in this study to prepare the uniformly oriented zeolite L monolayer with relatively high coverage degree and close packing degree. This could be ascribed to Substantial amounts of DICB self-assemble and standing on the Substrate Surface instead of folding Lip into a U-shape. This point has been further verified by the quality of oriented zoelite L monolayers obtained from the procedure involving DICB, 1, 4-bis (triethoxysilyl) benzene (BTSEB) and 1,2-bis(trimethoxysilyl)ethane (BTMSE) as covalent molecular linkers.
