摘要:

在水溶液中锡盐与β分子筛金属化过程中很容易水解为氢氧化物,因此,制备高度分散的、以孤立形式存在的锡物种非常具有挑战性.我们先采用SnCl2/氯化胆硷(ChCl)络合物将锡物种固定在高硅的商品化的β分子筛上,然后焙烧就可很方便地在水溶液条件下制得了高度分散于β分子筛上的锡物种.电镜照片、紫外-可见光光谱和X射线衍射结果证实了这一点.ChCl的存在促进了锡物种与分子筛的结合.担载(1-2)wt%Sn的β分子筛在葡萄糖-果糖异构化反应中表现出较高的催化活性和选择性.

Abstract:

Well dispersion of tin species in an isolated form is a quite challenge since tin salts are easily hydrolyzed into (hydr)oxides during aqueous stannation of β-zeolite. In this study, immobilization of tin species on high silica commercial β-zeolite by using SnCl2/Choline chloride (ChCl) complex followed with calcination provided a convenient way to get well dispersed Sn in β-zeolite in the aqueous condition, which was observed based on electron microscopy images, UV visible spectra and X-ray diffraction pattern. The existence of ChCl facilitated tin species to incorporate into zeolite. (1-2) wt% of Sn loaded β-zeolites exhibited good catalytic activity and high selectivity for glucose-fructose isomerization reaction.
