Abstract:

Recent advances in cooperative catalysis from adjacent acid sites in zeolite HZSM-5 is summarized in this review. The cooperativity is from the Br?nsted acid site and the Lewis acid site as well as from adjacent Br?nsted acid sites. Kinds of characterization are described for molecular adsorption, activation and transformation together with catalysis performance. The theoretical calculation is also performed to prove the cooperative catalysis. The challenge of studying the new facile pathway of cooperative catalysis is also raised up, and accurate measuring the distance of two acid sites and quantifing the amount of adjacent acid sites are pursued as well.

Key words: HZSM-5 zeolite, Lewis acid site, Br?nsted acid site, Cooperative adsorption, Cooperative catalysis
