Abstract
Piezo-photocatalysis is considered a promising pollutant treatment strategy. Herein, a simple strategy is proposed to construct lattice distortion in BiVO4 to realize an efficient piezo-photocatalytic degradation process. Specifically, the phase structure of BiVO4 is regulated by introducing different wavelengths of illumination, resulting in the homojunction formation. Compared with BiVO4 prepared under dark conditions (BVO), the VO bonds are shortened and the BiO bonds are elongated in the structure of BiVO4 synthesized under 460 nm illumination (BVO-460). Furthermore, the Tafel curve reveals that electrons flow from the monoclinic phase to the tetragonal phase. By the tetracycline hydrochloride degradation, it is found that the BVO-460 has excellent piezo-photocatalytic efficiency, attributed to the piezoelectric polarization field enhanced charge transfer. In this paper, the piezo-photocatalytic performance of BiVO4 is investigated in the insight of crystal phase structure, which provided a new idea for the application of layered bismuth-based materials in environmental purification.
