Beschreibung
Zusammenfassung:	The invention discloses a preparation method and application of a biochar copper manganese oxide self-cleaning coating based on photo-thermal concerted catalysis, relates to a preparation method and application of a self-cleaning coating, and aims to solve the problems that the sunlight absorption range of an existing carbon-loaded copper manganese oxide catalyst is relatively narrow; in order to solve the technical problems of low photothermal conversion efficiency, high heavy metal leaching risk and the like in the prior art, the preparation method of the self-cleaning coating provided by the invention comprises the following steps: 1, preparing a biomass charcoal carrier with a graphite nitrogen structure from nitrogen-rich agricultural wastes; 2, preparing a catalyst of biomass charcoal loaded copper manganese oxide; and 3, preparing the self-cleaning coating from a dispersing agent, the biomass charcoal loaded copper manganese oxide catalyst, silicone acrylic emulsion and water. The self-cleaning coating
