Uniform TiO2-SiO2 hollow nanospheres: Synthesis, characterization and enhanced adsorption-photodegradation of azo dyes and phenol

TiO2-SiO2 hollow nanospheres with remarkable enhanced photocatalytic performance have been fabricated by sol-gel method. The prepared photocatalyst displays high photocatalytic activity on methylene blue. And the nanocomposite of TiO2-SiO2 is a promising candidate material for future treatment of contaminated water.
