Annealing temperature effects on sol–gel nanostructured mesoporous TiO2/SiO2 and its photocatalytic activity
Under an Elsevier user license
open access
Highlights
▶ 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.
