Vapor-phase silylation for the construction of monomeric silica puncheons in the interlayer micropores of Al-MWW layered precursor.
Vapor-phase silylation of Al-MWW layered precursor with SiMe(2)Cl(2) and following calcination produced an interlayer-expanded MWW structure with 12-membered ring micropores without delamination as a result of the formation of silica puncheons between the MWW sheets; strong acidity of zeolitic nature was retained.
