Abstract

LiBiO₃, NaBiO₃, MgBi₂O₆, KBiO₃, ZnBi₂O₆, SrBi₂O₆, AgBiO₃, BaBi₂O₆ and PbBi₂O ₆ were synthesized by various processes such as hydrothermal treatment, heating and so on. These materials were examined for their photocatalytic activities in the decolorization of methylene blue and decomposition of phenol under visible light irradiation. For methylene blue decolorization, the presence of KBiO₃ resulted in complete decoloration within 5 min. For phenol decomposition, NaBiO₃ showed the highest activity, while LiBiO₃, SrBi₂O₆ and BaBi₂O₆ possessed almost comparable decomposition rates. Their decomposition rates were apparently higher than that by anatase (P25) under UV irradiation.
