Abstract
The yolk–shell structure Bi4−2xMoxO6 (x⩽1) microspheres were successfully synthesized via a simple solvothermal method. The morphology, structure and photocatalytic performances of the samples in the degradation of rhodamine B (RhB) and methyl orange (MO) were characterized by X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, UV–vis absorption spectroscopy and electrochemical impedance spectra, respectively. The results show that the yolk–shell structure Bi2.38Mo0.81O6 microspheres exhibit the best photocatalytic performance for the degradation of RhB and MO with a degradation rate of 99% and 72% under visible light irradiation.
