通过后处理将氟物种成功地注入MWW型钛硅酸盐中，在沸石骨架中产生SiO 3/2F单元。引入的氟物种由于提高了分子筛的刘易斯酸强度和疏水性而显著改善了烯烃环氧化反应的催化性能。
Fluorine species were successfully implanted into a MWW-type titanosilicate via post-treatment, which generates the SiO3/2F units in the zeolite framework. The incorporated fluorine species significantly improved the catalytic performance in the epoxidation of alkenes as a result of enhancing the Lewis acid strength and the hydrophobicity of the zeolite.
