Room temperature synthesis of one-dimensional hierarchical hollow BiOBr with tunable photocatalysis reaction pathway for RhB under visible light.

One-dimensional (1D) hierarchical photocatalyst has the advantages of 1D materials and hierarchical materials, which is a kind of potential high performance photocatalytic materials. However, how to efficiently synthesize 1D hierarchical BiOBr is still a huge challenge. Herein, 1D rod-like BiO(OH)(NO)·3HO, the hydrolysis product of Bi(NO)·5HO, was acted as both the template and Bi source to synthesize 1D hierarchical hollow BiOBr (1DHHBr) through a facile solution stirring method at room temperature, using KBr as Br source.
