Mesoporous silica fiber was synthesized by sol-gel process and centrifugal spinning method. The spinning process induced lattice contraction and also promoted the oderness of the mesoporous structure. The fiber is 3-10 cm in length and optically transparent. TiO2 was loaded on the mesoporous silica fiber by simple impregnation method. The volume of 1nm pore was decreased by the formation of TiO2 particles in the meso-pores of silica fiber. The TiO2 / mesoporous silica fiber showed the absorption band around 300 - 350 nm which has been assigned to the crystalline TiO2 phase. The photocatalytic activity of TiO2 loaded mesoporous silica fiber was much higher than conventional TiO2 / mesoporous silica powder and commercial TiO2 (P-25). The mesoporous silica fiber seems to be promising support for the practical application of photocatalytic reaction.
