摘要: 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 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 investigated, which suggests that OH− plays vital role forming by affecting release of VO3−. results this study provide available means preparation photocatalyst film.
