摘要：

Quasi-solid-state crystallization was used to prepare zeolite TS-1 catalysts with micro-meso-macroporous (MMM) structure (see picture) and improved stability. They show a well-defined macroporous structure and an interconnected mesoporous network made of uniform zeolite TS-1 nanocrystals. The hierarchical pore structure and high stability result in superior catalytic activity in the epoxidation of larger molecules such as 2,4,6-trimethylstyrene.
