Abstract
The photogenerated carriers of BiVO4 are easily recombined and desired to be improved effectively. In this paper, the separation degree was improved by prolonging the cooling time in the process of BiVO4 synthesis. When the cooling rate was 50 °C h−1, the performance of BiVO4 particles was significantly optimized, including the highest peak of (040) facets, the improvement of morphology, the increase of carriers separation and the optimum degradation of doxycycline. When the degradation time was only 15 min, doxycycline in water could be effectively removed with a removal rate of 63%. These studies are valuable for improving the chemical properties of BiVO4 and broadening its application.
