Yellow colored anatase Fe/N co-doped TiO2powders have been successfully synthesized by one step hydrothermal method at a lower temperature. The grain size was about 10 nm and the specific surface area of the powders ranged from 160 to 166 m2/g. The light absorption of Fe/N co-doped TiO2powders was enhanced in the visible light region of 400~500 nm and a new absorption peak at about 470 nm appeared when the Fe/Ti ratio exceeded 0.5%. The visible light photoactivity of Fe/N co-doped TiO2powders has been greatly improved than that of un-doped TiO2powders under visible light irradiation.
The novel Z-scheme Ag3VO4/Ag4V2O7 heterojunction photocatalysts which constructed by one-step hydrothermal method had stable visible-light-driven photocatalytic performance and high efficiency.
Flowerlike MoS2/CdS heterostructures are prepared by a simple hydrothermal method and they show higher photocatalytic activity under the excitation of visible light.
