Abstract:

Precise control of crystal growth allows for zeolites with tailored morphology, and one of the typical zeolite families is one-dimensional zeolites such as ZSM-23, which normally displays a needle-like morphology with micron-level length. This morphology not only strongly influences catalytic performances but also has potentially healthy issue. Herein, we for the first time show a successful synthesis of ZSM-23 zeolite nanosheets with a thickness of only about 10 nm from a novel gemini-type quaternary ammonium as an organic template. Characterizations of the samples demonstrate that ZSM-23 zeolite nanosheets along a and b axes have high crystallinity, large external surface area, and fully four-coordinated aluminum species. Very importantly, ZSM-23 zeolite nanosheets exhibit higher n-hexadecane (C16) conversion and iso-C16 yield in n-C16 hydroisomerization than those of conventional ZSM-23 zeolite synthesized from N,N-dimethylformamide. These findings offer a favorable opportunity for the subsequent development of efficient zeolite catalysts in the future.
