BiOX (X=Cl, Br, I) nanostructures: Mannitol-mediated microwave synthesis, visible light photocatalytic performance, and Cr(VI) removal capacity

Bi5 O7 I Nanobelts: Synthesis, Modification, and Photocatalytic Antifouling Activity

Bi5 O7 I 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 Bi5 O7 I nanobelts was proposed. To enhance the photocatalytic antifouling activity, ethanol or TiCl3 was used to modify the Bi5 O7 I nanobelts. The resulting BiOI/Bi2 O2 CO3 /Bi5 O7 I and TiO2 /BiOCl/Bi5 O7 I 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.
