Abstract

Bi₂WO₆ prepared by hydrothermal method were treated by H₂SO₄ with different concentrations.And Bi₂WO₆ with Bi defect was synthesized through the corrosion of H₂SO₄.The degradation activity of the catalyst to toluene was explored under visible light.The results showed that Bi₂WO₆ treated with 1M H₂SO₄ showed better photocatalytic degradation effect than pure Bi₂WO₆,and the degradation rate can reached 82% in 180min under visible light.This is mainly because Bi-deficient Bi₂WO₆ has a large number of protonated —OH groups around it under the strong protonation force of H₂SO₄,which can effectively capture photogenerated electrons and improve the separation efficiency of electron-interaction.
