Abstract: Mesoporous silicas have been widely used in the field of adsorption-separation because of their large surface areas，pore volume，diameters，and highly ordered pore structure. In this paper，the modification methods of mesoporous silicas，including incorporation，impregnation，and the synthesis of silica-based mesoporous organic-inorganic hybrid materials，are reviewed. Recent studies on the application of mesoporous silicas in the adsorptive desulfurization of fuel，natural gas，coal gas，H2S，and SO2 are summarized. Meanwhile，the outlook on the modification of mesoporous silicas is proposed. The synthesis of new silica-based mesoporous organic-inorganic hybrid materials and their applications in adsorption areas are in the primary trend.
