Carbon heterogeneous surface modification on a mesoporous TiO_2-supported catalyst and its enhanced hydrodesulfurization performancet

摘要

In this work, we report a novel surface modification which can improve the desorption of a hydrodesulfurization product (H_2S) from mesoporous TiO_2. The corresponding catalyst exhibits a significantly enhanced hydrodesulfurization performance compared with an unmodified catalyst, and the dibenzothiophene conversion increases from 65% to 98%.
