eng Effect of hierarchical pores existence in zeolites in their Bronsted acidity Aim of this work was to study strength of acid sites of zeolites both purely microporous and hierarchical micro/mesoporous character of the same crystalline structure. Zeolitic materials of MWW topology having purely microporous character (MCM-22 and MCM-49) and layered disordered character (MCM-56) or pillared form (MCM-36) were investigated. In addition, classical 3D MFI zeolite and its 2D analogues (self-pillared zeolite nanosheets or desilicated hierarchical MFI zeolite) were also investigated. Acidity of the zeolites was estimated by ammonia temperature programmed desorption technique. acid site; zeolite; NH3 desorption
