Herein, the BiVO4/α, β-Bi2O3 nanofibers with moderate amounts of BiVO4 nanoparticles (1-5 wt%) were successfully fabricated by combining electrospinning and hydrothermal method. The microstructure and properties of the prepared samples were characterized by X-ray diffraction, X-ray photoelectron spectro- scopy, fourier transform infrared spectrometer, scanning elec- tron microscopy, transmission electron microscope, ultraviolet- visible diffuse reflection, and photocurrent measurement. The results show that BiVO4 had a substantial effect on the formation of β-Bi2O3 and the structure of the nanofibers. From the photocatalytic test results, it can be inferred that the RhB degradation efficiencies of pure BiVO4 and α-Bi2O3 were lower than those of the composites considered in this study. The samples with a BiVO4 content of 3 wt% displayed the best photocatalytic activity for RhB (the degradation efficiency of RhB and Tc was 96.1% and 77.1%, respectively) compared to that of other samples considered in this study.
