Abstract

Sillenite-type Bi₂₅GaO₃₉ as an efficient photocatalyst was studied in the present paper. The compound synthesized by a solid state reaction method has a band gap of 2.95 eV. It possesses a fair visible-light-response ability. The UV-light-induced photocatalytic activities for degrading methylene blue follow the decreasing order of anatase TiO₂ > Bi₂₅GaO₃₉ > Bi₁₂GeO₂₀ > Bi₂₄Ga₂O₃₉, different from Bi₁₂GeO₂₀ > Bi₂₅GaO₃₉ > Bi₂₄Ga₂O₃₉ > TiO₂ under visible light irradiation. The dispersion of Pt over Bi₂₅GaO₃₉ leads to an obvious increase in photocatalytic performance. The opener structure of Bi₂₅GaO₃₉ is proposed to explain the higher UV-light-induced photocatalytic activity, compared with Bi₂₄Ga₂O₃₉ and Bi₁₂GeO₂₀.
