Description
Summary:The synthesis of zeolite nanosheets is an effective strategy to obtain advanced catalysts with enhanced catalytic performance due to the improved diffusion properties. ZSM-22 zeolite nanosheets (F-ZSM-22, U-ZSM-22) with a controllable orientation and a thickness of less than 20 nm were obtained through hydrothermal crystallization by introducing NaF or urea into the synthetic system of conventional ZSM-22 (C-ZSM-22). In the presence of both NaF and urea, a zeolite nanosheet (FU-ZSM-22) with a decreased width was synthesized. In comparison with C-ZSM-22, all ZSM-22 nanosheets displayed better diffusion properties. On testing catalysts in the methanol-to-hydrocarbon reaction, ZSM-22 nanosheets showed better stability than C-ZSM-22, and FU-ZSM-22 was the best catalyst.
