Preparing and catalytic performance of a novel titanosilicate with FER topology

Abstract

Ti-PLS-3, a kind of layered titanosilicates of FER topology was developed by hydrothermal synthesis with the help of using pure silica PLS-3 as seed. The Si/Ti ratio of this material can be adjusted in a wide range from 20 − ∞. The structure and active sites of Ti-PLS-3 were detected by various characterization. After mild acid treatment to eliminate the hexa-coordinated extra-framework Ti species, the resulting material turned out to be a more effective catalyst for epoxidation of 1-hexene with H _2 O _2 than reported FER type Ti-containing material Ti-FER.
