title: Bi5O7I Nanobelts: Synthesis, Modification, and Photocatalytic Antifouling Activity.
abstract: Bi5O7I nanobelts were prepared by a facile hydrothermal method to study the crystal phase transformation and morphology evolution. Based on these results, a crystal growth mechanism of Bi5O7I nanobelts was proposed. To enhance the photocatalytic antifouling activity, ethanol or TiCl3was used to modify the Bi5O7I nanobelts. The resulting BiOI/Bi2O2CO3/Bi5O7I and TiO2/BiOCl/Bi5O7I micro-nanostructures show excellent degradation activity of malachite green and bactericidal effects against Pseudomonas aeruginosa, which may be attributed to the higher charge carrier separation efficiency of these heterojunction structures. The results indicate that the formation of semiconductor composites is a very effective strategy to design high-performance photocatalyst systems.
