Description: 
In this study we employed hydrogen peroxide etching of Ti films as a straightforward method to synthesize hydrogenated TiO2 nanoplumes. The material was extensively characterized, showing, among other special features, the inclusion of OH groups. These groups together with the generated structural defects and the nanostructuration are crucial for the high photocatalytic properties under ultraviolet (UV) and visible (VIS) light irradiation. In particular, nanoplumes show a reaction rate about 5 times the rate of TiO2 flat films. Furthermore, nanoplumes display a significant antibacterial activity under VIS light irradiation, compared with TiO2 films.
