| description | The invention discloses a preparation method and application of bismuth oxychloride with a function of adjusting the position of an energy band, and belongs to the technical field of environmental protection and pollutant degradation. According to the preparation method, a mixed solvent composed of any more of ethyl alcohol, ethanediamine, diethylene glycol and triethylene glycol is utilized to replace existing ethyl alcohol as a reaction solvent, and a BiOCl material with a down-shifted valence band is prepared through a solvothermal reaction. The oxidizability of photo-generated h of theBiOCl material with the down-shifted valence band is stronger, which is more conductive to degrading pollutants; in addition, the h with the strong oxidizability can activate H2O2 to generate O2, and the photodegradation efficiency is further improved. A photodegradation effect shows that the degradation rate of BiOCl for rhodamine B, methyl orange and phenol is increased by 3.2-4.6 times after the H2O2 is added.
