文摘

Three ZnO catalysts supported on zeolites were synthesized by the humid impregnation method. In the larger pore size of zeolites, ZnO was included into the micropores. BET analysis indicates reduction of specific surface area. ZnO formed needle-shaped crystallites on NaA zeolite. Bandgap values of the catalysts in NaA and NaY are close to the pure ZnO.
