A simple one step wet-chemical method assisted by trisodium citrate was employed in the synthesis of BiOBr applied as a photocatalyst. Photocatalytic activity of the BiOBr was investigated for the degradation of Rhodamine B (RhB) dye under visible light irradiation (>420 nm). The results indicated that trisodium citrate is more favorable to the formation of hierarchical architectures and reduces the particle size of BiOBr photocatalyst. BiOBr with hierarchical architectures exhibiting significantly higher catalytic activity than that with ordinary nanostructure. The significant improvement could be attributed to the high specific surface area (24.14m2·g1), average pore sizes (34.09 nm) and average pore volume (0.24 cm3·g1).

A Bi6O6(OH)3(NO3)3·1.5H2O (BBN)/Bi2O2CO3 (BOC) heterojunction was designed for the first time via afacile hydrothermal method. The photocatalytic performance of catalysts was evaluated by degrading Rhodamine B(RhB) under simulated solar light irradiation. It was found that the degradation rate of RhB by 25 wt%BBN/BOC wasdramatically increased about 1.5 and 4.7 times compared with that of pure BOC and BBN, respectively. The enhancedphotocatalytic performance migth be attributed to the effective separation of photoinduced electron-hole pairs, benefitingfrom the construction of heterojunction. Furthermore, the mechanism upon BBN/BOC composites photocatalystwas investigated, expecting this work will bring new insight into the theoretical study and application of semiconductorsmaterials.
