Mass Production of Bi3NbO7 / Bi2Zn2/3Nb4/3O7 composites and their visible-light photocatalytic activity

Series Bi 3 NbO 7 /Bi 2 Zn 2/3 Nb 4/3 O 7 (BN/BZN) composites were synthesized through a facile solid state reaction method. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-vis diffuse reflectance spectroscopy(DRS). When BN: BZN...

Summary:Series Bi 3 NbO 7 /Bi 2 Zn 2/3 Nb 4/3 O 7 (BN/BZN) composites were synthesized through a facile solid state reaction method. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-vis diffuse reflectance spectroscopy(DRS). When BN: BZN=0.1 mole ratio, the BN/BZN composite showed the best visible-light-driven photocatalytic performance, which decomposed nearly 100% of RhB (10 ppm, pH=3-4) within 40 min. The results demonstrated that in-situ solid state synthesis of BN/BZN composites could be an efficient strategy to develop new photocatalyst for environmental remediation.
