Abstract
A fish bone-like BiVO4 film was successfully prepared in-situ on metal Bi substrate via a facile one-step hydrothermal method. The obtained BiVO4 film exhibits excellent tetracycline photodegradation efficiency, reaching 89.7% in 240 min under visible light irradiation. Its quantum yield (6.3 × 10−5 molecules photon−1) and kinetic reaction rate (7.80 μmol g−1 h−1) are better than most reported immobilized Bi-based systems. Finally, the formation mechanism was investigated, which suggests that OH− plays a vital role in forming BiVO4 film by affecting the release of VO3−. The results of this study provide available means in the in-situ preparation of Bi-based photocatalyst film.
