Composite zeolites,especially micro/microporous composites,have been paid more and more attention due to their synergistic performances in catalytic reactions [
Zeolite-microporous crystalline aluminosilicates as a class of size-and shape-selective catalysts are widely used in petrochemistry and fine-chemical synthesis.
Recently,we have developed a new synthesis route to hierarchical zeolites,which is based on the etching in fluoride medium.1 The major advantage of this approac
