英文摘要	Hierarchical zeolite materials were prepared via one-pot synthesis of ZSM-11 zeolites with different molar ratios (R) of a mesoporogen, i.e., cetyltrimethylammonium bromide template (CTAB), to a microporogen, i.e., tetra-n-butylammonium bromide (TBABr). The structures, morphologies, and textural properties of the resultant materials were investigated. Initially, with increasing R, the crystal size of the synthesized product decreased, the number of intercrystalline mesopores increased, and a pure ZSM-11 zeolite phase was present Then an MCM-41-like phase was produced and embedded in the ZSM-11 zeolite phase. Finally, an MCM-41-like phase was obtained. The alkalinity had important effects on the physicochemical and textural properties of the prepared samples. A possible mechanism of formation of the hierarchical ZSM-11 zeolite was proposed on the basis of a combination of various characterization results. The role of CTAB varied depending on the R value, and it showed a capping effect, micellar effect, and template effect These effects of CTAB were synergetic in ZSM-11 synthesis, but they were competitive with the structure-directing effect of TBABr. In addition, the impact of the acidic properties and porosities of the hierarchical ZSM-11 catalysts on their performances in the alkylation of benzene with dimethyl ether was investigated.
