Abstract
High-resolution TEM micrograph of Ti-containing SBA-16-type mesoporous material prepared by the evaporation-induced self-assembly method.
A novel Ti-containing SBA-16-type mesoporous material (with various Ti loadings of 5, 10, and 15
wt%) was synthesized by an evaporation-induced self-assembly method using F127 copolymer as template. The materials were characterized by XRD, FTIR, TG–DTA, N
2 adsorption, SEM, HRTEM, and XPS. The characterization results show that the material possesses high thermal stability, thick pore walls (10.43–10.68
nm), and high surface area (642.26–691.5
m
2/g) with a mesoporous worm-like structure, and titanium was successfully incorporated into the silica matrix with a tetrahedral environment. The material showed high activity in the oxidative desulfurization of DBT and its activity was not reduced even after three times recycling; further reuse resulted in a gradual decrease in its activity.
