Hollow ZSM-11 was successfully prepared through post-treatment with tetrabutylammonium hydroxide (TBAOH). The products were characterized by XRD, TEM, ICP-OES, 27Al NMR, 27Si NMR, N2 physical adsorption and NH3-TPD and studied as catalysts for the reaction of methanol to hydrocarbons. The characterization results showed that the hollowness might be formed through a dissolution–recrystallization process. The hollow ZSM-11 zeolite showed higher specific surface areas, higher external surface areas, higher mesopore volumes and more acid sites than the untreated ZSM-11, and exhibited excellent catalytic properties in the reaction of methanol to hydrocarbons.
