Hydrothermal synthesis of CuBi2O4 nanosheets and their photocatalytic behavior under visible light irradiation

CuBi2O4 with various novel morphologies were successfully prepared via a hydrothermal process. The results showed that some prepared samples exhibited a novel leaf-like nanosheet morphology with a uniform spinel CuBi2O4 structure, and their excellent visible light absorption characteristics, the photocatalytic properties exhibited a strong dependence on nanocrystal microstructure, morphology and lattice orientation.
