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.
