Title	Synthesis of Mesoporous TS-1 for Catalytic Oxidative Desulfurization
Author	Chul Woo Park, Tae Kyung Kim, Wha Seung Ahn*
Keywords	Mesoporous TS-1, CMK-3, Carbon black, Oxidative desulfurization
Abstract	Mesoporous TS-1 catalysts were prepared via a nanocasting route using two different carbon template sources of CMK-3 and commercial carbon black. Products were characterized by XRD, UV-Vis spectroscopy, SEM, TEM, and N₂ adsorption- desorption measurement. The catalytic performances of the samples for allylchloride epoxidation and oxidative desulfurization of the representative refractory sulfur compounds, dibenzothiophene and 4,6-dimethyldibenzothiophene, were compared against those of conventional TS-1. Whilst the allychloride epoxidation activity for the mesoporus TS-1 samples were similar, mesoporous TS-1 exhibited significantly higher catalytic activities than conventional TS-1 in oxidative desulfurization.
