A facile approach was developed to synthesize novel Roe-like TiO2 hollow nanospheres via a template-assisted self-assembly process. These TiO2 nanospheres possessing mesoporous cavity manifest significantly improved photocatalytic activity owing to the synergistic effects of increased charge separation, more efficient use of the light and specific surface area.

Flower-like rutile TiO2 mesocrystals were synthesized by a K2TiO(C2O4)2-mediated low temperature solution route under the atmospheric pressure, which exhibited high photocatalytic activity because of the large specific surface area as well as the high charge separation rate inherent from the single crystal nature.

Stannic oxide-titanium dioxide (SnO2–TiO2) coupled semiconductor photocatalyst loaded with polyaniline (PANI), a conducting polymer, possesses a high photocatalytic activity in oxidation of 1-octene to 1,2-epoxyoctane with aqueous hydrogen peroxide. The photocatalyst was prepared by impregnation ofSnO2and followed by attachment of PANI onto aTiO2powder to give sample PANI-SnO2–TiO2. The electrical conductivity of the system becomes high in the presence of PANI. Enhanced photocatalytic activity was observed in the case of PANI-SnO2–TiO2compared to PANI-TiO2,SnO2–TiO2, andTiO2. A higher photocatalytic activity in the oxidation of 1-octene on PANI-SnO2–TiO2thanSnO2–TiO2, PANI-TiO2, andTiO2can be considered as an evidence of enhanced charge separation of PANI-SnO2–TiO2photocatalyst as confirmed by photoluminescence spectroscopy. It suggests that photoinjected electrons are tunneled fromTiO2toSnO2and then to PANI in order to allow wider separation of excited carriers.
