Electrochemical performance and enhanced photocatalytic activity of Ce-doped BiVO4 under visible light irradiation
Source abstract
Abstract
Abstract Ce-BiVO 4 composites have been synthesized via a simple precipitation-impregnation method and were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), UV–vis diffuse reflectance spectrum (DRS), electrochemical impedance spectrum (EIS) and photocurrent. All the BiVO 4 and Ce-BiVO 4 samples are composed of monoclinic scheelite BiVO 4 . Compared to BiVO 4 , the increased photocurrent and decreased diameter of the semicircle have been observed for Ce-BiVO 4 , indicating that the Ce-doping can enhance interfacial electron transfer for Ce-BiVO 4 . Ce-BiVO 4 composites show enhanced activity in the photocatalytic degradation of rhodamine B under visible light irradiation in comparison with P25 and pure BiVO 4 , and 1.0%Ce-BiVO 4 shows the best photocatalytic activity because of its enhanced light absorption, narrowed bandgap and improved separation of the photogenerated electron–hole pairs, which was achieved as a result of photogenerated electrons transfer from the BiVO 4 to the Ce 4+ ions.
