The presence of small amount of fluoride in alkaline hydrothermal synthesis of SSZ-13 zeolite yields bimodal microporous particles with substantially improved performance in the methanol-to-olefins (MTO) reaction. Hydrocarbon uptake measurements and fluorescence microspectroscopy of spent catalysts demonstrate enhanced diffusion through micropores at the grain boundaries of nanocrystals running through the zeolite particles. Fluoride-assisted SSZ-13 synthesis is a cheap and scalable approach to optimize the performance of MTO zeolite catalysts.
在SSZ-13沸石的碱性水热合成中存在少量氟化物会产生双峰微孔颗粒，其在甲醇制烯烃（MTO）反应中的性能有显著改善。对废催化剂的烃类吸附测量和荧光显微光谱表明，通过贯穿沸石颗粒的纳米晶体晶界处的微孔，扩散得到了增强。氟化物辅助的SSZ-13合成是一种优化MTO沸石催化剂性能的廉价且可扩展的方法。
