Postsynthesis and catalytic properties of metallosilicates structurally analogous to MCM-56
A novel postsynthesis method for preparing various metallosilicates structurally analogous to MCM-56 has been developed. Highly crystalline MCM-56 zeolites were postsynthesized readily from corresponding MWW type lamellar precursors by a simple acid treatment at controllable temperatures. The titanosilicate analogue, Ti-MCM-56, thus obtained has been characterized by various techniques and applied to the liquid-phase oxidation of alkenes in comparison to three-dimensional (3D) Ti-MWW and Ti-Beta. Ti-MCM-56 with an open external surface showed a much higher activity for bulky molecules than Ti-MWW.
