摘要：
In this research, Bi2WO6 nanoplates doped with 0, 1, 3 and 4% by weight of Mo were successfully synthesized by hydrothermal method. X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and ultraviolet-visible spectroscopy certified that the as-synthesized products were uniform orthorhombic Bi2WO6 nanoplates with absorbance of the pure product in ultraviolet region and of the doped ones in both ultraviolet and visible regions. Photocatalysis of the products was also evaluated through the degradation of rhodamine B under visible light irradiation. The Bi2WO6 nanoplates doped with 3% by weight of Mo have the highest rate constant of 0.023 min(-1). (c) 2018 The Ceramic Society of Japan. All rights reserved.
