Annealing temperature effects on sol-gel nanostructured mesoporous TiO2/SiO2 and its photocatalytic activity

▶ Mesoporous TiO2/SiO2 synthesized by the sol-gel method and thermally treated. ▶ Thermally stable anatase TiO2 nanoparticles highly dispersed in the SiO2 matrix. ▶ Relations between number of structural defects and short-distance ordering of TiO2. ▶ Relationship of the photocatalytic performance with the structural features.
