【 摘 要 】

A new heterojunction BiOXs/TiO 2 photocatalyst was firstly prepared by a mixed solvothermal method. Several tools were used to characterise the structure and morphologies of as-obtained samples. The results of photocatalytic experiments indicated that flower-like BiOXs/TiO 2 fabricated by the thinner nanosheets exhibited excellent degradation properties towards methyl orange, bisphenol A and tetracycline under visible-light irradiation. The reasons could be the good absorption of organic pollutants and light, and the high separation efficiency of photogenic electrons and holes attributed to the construction of BiOXs/TiO 2 heterojunction with large special surface areas. The photocatalytic mechanism was proposed. This Letter could provide new ideas to design the visible-light catalysts.
