Visible Light-Driven Photocatalytic Performance of N-Doped ZnO/g-CN Nanocomposites.

N-doped ZnO/g-CN composites have been successfully prepared via a facile and cost-effective sol-gel method. The nanocomposites were systematically characterized by XRD, FE-SEM, HRTEM, FT-IR, XPS, and UV-vis DRS. The results indicated that compared with the pure N-doped ZnO, the absorption edge of binary N-doped ZnO/g-CN shifted to a lower energy with increasing the visible-light absorption and improving the charge separation efficiency, which would enhance its photocatalytic activity.

The Antibacterial Activity of Ta-doped ZnO Nanoparticles.

A novel photocatalyst of Ta-doped ZnO nanoparticles was prepared by a modified Pechini-type method. The antimicrobial study of Ta-doped ZnO nanoparticles on several bacteria of Gram-positive Bacillus subtilis (B. subtilis) and Staphylococcus aureus (S.

Preparation, characterization and photocatalytic properties of ZnTiO3 powders.

A novel photocatalyst ZnTiO(3) powder was prepared by a modified alcoholysis method, using ethylene glycol as reagent/solvent and acetylacetone as stabilizer. A series of analytical techniques were used to characterize the crystallinity, composition, bandgap, morphology, specific surface area and grain size of ZnTiO(3) powders. The relationship between the physicochemical property and the photocatalytic activity was deeply investigated, too.
