Beschreibung
Zusammenfassung:	The invention discloses a PDA/BiOCl photocatalytic material as well as a preparation method and application thereof, and belongs to the technical field of antibacterial agents. The preparation method comprises the following steps: step 1, preparing an aqueous solution containing a bismuth source to obtain a clear solution A; 2, dissolving a halogen source in a buffer solution, controlling the pH value of the solution to be 7.5-9.5, and standing at room temperature to obtain a solution B; and step 3, slowly dropwise adding the clear solution A obtained in the step 1 into the solution B obtained in the step 2, continuously stirring and reacting to obtain a precipitate, washing and drying to obtain the PDA/BiOCl photocatalytic material, PDA in the prepared photocatalytic material is of a polymer network structure and coats BiOCl petal-shaped particles, and the photocatalytic material has higher visible light utilization efficiency, and can be used for preparing the photocatalytic material. The excellent photocat
