Synthesis of size-controlled silica-supported TiO2 photocatalysts

Supported nanocrystalline titanium dioxide has been prepared by a sol-gel method through the use of mesoporous silica materials. The work has been addressed to study the effect of the different type of silica support on the mean titania particle size and their effect in the photocatalytic activity....
