摘要

Sb₂O₃/BiVO₄/WO₃ semiconductor heterojunctions were constructed by solvothermal method and spin coating method, and X‐ray diffraction, scanning electron microscopy, and X‐ray photoelectron spectroscopy were used to characterize the physical and chemical properties. The photocurrent density of BiVO₄/WO₃ was increased by two times compared with BiVO₄ at 1.23 V (vs RHE). Although further coating with Sb₂O₃ decreased the photocurrent density of Sb₂O₃/BiVO₄/WO₃ film, the Faraday efficiency and production rate of H₂O₂ were improved. At 1.89 V (vs RHE), the Faraday efficiency of 3c‐Sb₂O₃/BiVO₄/WO₃ film was enhanced to ca. 19%; the production rate of H₂O₂ of 1c‐Sb₂O₃/BiVO₄/WO₃ film increased from ca. 2.1 to ca. 3.6 μmol·h^-1·cm^-2. In addition, the coating of Sb₂O₃ significantly improved the photoelectrocatalytic stability of BiVO₄/WO₃ electrode.
