Bismuth oxide-based semiconductor materials possess a unique layered structure with alternate [Bi_2O_2]~(2+) and [Cl2]layers,and an adjustable band gap, showing superior performance and great potential in the solar-light-driven environmental pollutants removal.On account of the relevant research progress of others and our latest research results,the research results on the photocatalytic removal of environmental pollutants with bismuth oxyhalide (bismuth oxychloride,bismuth oxybromide and bismuth oxyiodine)are summarized,mainly including the fabrication and modification strategies of bismuth o...
