Plate-like TS-1 zeolites offering a short diffusion pathway along the axis are highly desirable catalysts in the reaction of alkene epoxidation. Herein, we successfully developed a simple synthetic strategy toward reducing the thickness along the -axis of TS-1 zeolite crystals, -lysine adopted as a zeolite growth modifier was firstly proposed to prepare plate-like TS-1 zeolite. Meanwhile, through tuning the preliminary aging time, plate-like TS-1 zeolites with thickness in the range of 80–1000 nm can be controllable obtained. In this work, the synthesis parameters controlling the formation of plate-like TS-1 zeolites are studied, and the factors controlling the zeolite growth were well elucidated. Compared with the conventional TS-1 zeolite as well as the plate-like TS-1 synthesized in the fluoride-containing medium, the obtained plate-like TS-1 shows improved catalytic performances in catalyzing epoxidation of 1-hexene.

赖氨酸辅助合成片状 TS-1 沸石用于 1-己烯环氧化


板状 TS-1 沸石提供沿轴的短扩散路径，是烯烃环氧化反应中非常理想的催化剂。在此，我们成功地开发了一种减少TS-1沸石晶体沿β轴厚度的简单合成策略，首次提出采用γ赖氨酸作为沸石生长调节剂来制备片状TS-1沸石。同时，通过调节预老化时间，可以可控地获得厚度在80~1000 nm范围内的片状TS-1沸石。本工作对控制片状TS-1沸石形成的合成参数进行了研究，并很好地阐明了控制沸石生长的因素。与传统的TS-1沸石以及在含氟介质中合成的片状TS-1相比，所获得的片状TS-1在催化1-己烯环氧化方面表现出改善的催化性能。
