Photocatalysis: Light-Switchable Oxygen Vacancies in Ultrafine Bi5O7Br Nanotubes for Boosting Solar-Driven Nitrogen Fixation in Pure Water (Adv. Mater. 31/2017)

Hao Chen, Jinhua Ye and co-workers develop a self-assembled 5-nm-diameter Bi₅O₇Br nanotubes for N₂ fixation in water. They reveal in article number 1701774 that, under visible light irradiation, partial O atoms will escape in the form of O₂ from the surface of ultrafine Bi₅O₇Br nanotubes, creating light-switchable OVs-rich ultrafine Bi₅O₇Br nanotubes, which are responsible for the excellent photocatalytic N₂ fixation activities.
