| titleOfInvention | C3N4@Ag3PO4Preparation and application of/PDA @ PVDF bionic composite catalytic membrane |
| abstract | The invention belongs to the technical field of environment functional materials, and relates to a C 3 N 4 A preparation method and application of the composite catalytic membrane. First AgNO 3 And g-C 3 N 4 Dissolving in water to obtain solution A, adding Na 3 PO 4 Dripping the solution into the solution A, stirring, washing, centrifugally separating and drying to obtain a binary composite semiconductor material C 3 N 4 @Ag 3 PO 4 (ii) a Then dissolving dopamine in a Tris-HCl solution, placing a PVDF membrane in the solution, modifying the dopamine to enable a polydopamine layer to be deposited on the surface of the PVDF membrane, and drying the obtained polydopamine modified membrane (PDA @ PVDF) at room temperature; c is to be 3 N 4 @Ag 3 PO 4 Dissolving in water, and ultrasonic dispersing to obtain C 3 N 4 @Ag 3 PO 4 And (3) taking PDA @ PVDF as a base film, carrying out vacuum filtration, and drying at room temperature. The silver phosphate nano material loaded with the graphite and nitrogen carbide nanosheets forms point-surface contact, thereby inhibiting C 3 N 4 Recombination of photo-generated electron-hole pairs and increase of Ag 3 PO 4 Further improving the photocatalytic activity, adding C 3 N 4 @Ag 3 PO 4 The catalyst is loaded on the PVDF membrane, so that the problems that the catalyst powder is difficult to recycle and easy to waste are solved, the problem that membrane pores are blocked due to membrane pollution is solved, and the removal rate of pollutants is improved. |
