The invention discloses a photocatalytic formaldehyde-removing modification catalyst, a preparation method and an application thereof. A method for preparing a photocatalytic formaldehyde-removing modified catalyst comprises: taking urea for grinding, putting it into a muffle furnace for calcination, and naturally cooling it to room temperature to obtain g-C 3 N 4 ; dispersing g-C 3 N 4 in a DMF solvent In the mixture of dehydrated alcohol, then ultrasonic treatment, then add cobalt acetate tetrahydrate, polyvinylpyrrolidone and pyrazine, and obtain mixture A after stirring; Disperse TCPP in the mixture of DMF solvent and dehydrated alcohol to obtain mixture B; The mixture B was added to the mixture A and stirred, and then transferred to a polytetrafluoroethylene-sealed autoclave for reaction. Finally, the resultant was washed several times with ethanol, and the precipitate was dried to obtain a photocatalytic removal of formaldehyde. Modified catalyst. The photocatalytic formaldehyde-removing modification catalyst is prepared by the preparation method of the photocatalytic formaldehyde-removing modification catalyst. The invention also provides the application of a photocatalytic formaldehyde-removing modification catalyst. |
