The invention discloses a metal ion co-doped BiOBr microsphere, a preparation method and an application thereof. The microsphere is specifically Bi 1-x- y Cd x Fe y OBr, wherein x=y=0.02, or Bi 1- x Cd x OBr, where x=0.02, or Bi 1-x F x OBr, where x=0.02, the preparation method comprises dissolving the bismuth source and CTAB in an organic solvent, respectively, ultrasonically treating, magnetic stirring; mixing to obtain a mixed The solution was added with metal ions, transferred to an autoclave, and a bursting membrane was added to carry out a microwave hydrothermal reaction; after the reaction, the product was cooled to room temperature, washed several times with deionized water, fully washed with ethanol, and dried. The preparation method of the invention has mild conditions and simple process, and can efficiently degrade organic pollutants such as dyes and antibiotics in sewage under simulated sunlight irradiation. |
