In Situ Growth of Metal–Organic Framework on BiOBr 2D Material with Excellent Photocatalytic Activity for Dye Degradation

The in situ growth of Bi-based metal–organic framework (MOF) (CAU-17) on BiOBr 2D material was prepared for the first time by using a facile solvothermal transformation approach. The BiOBr was applied both as template to support the growth of MOF and as Bi3+ source of MOF. The BiOBr/CAU-17-2h composite exhibited enhanced photocatalytic activity for degradation of Rhodamine B (RhB), methylene blue (MB), and methyl orange (MO) under visible light irradiation, suggesting a good synergy between BiOBr and CAU-17 MOF.
