Abstract
A high-efficiency visible-light catalytic material, a preparation method and an application thereof are provided by the present application, relating to the technical field of photocatalytic materials. The present application prepares photocatalytic material Ag@AgCl/CA by compounding Ag@AgCl and calcium alginate gel, and the prepared photocatalytic material is shaped as small particles. The photocatalytic material Ag@AgCl/CA is used to degrade tetracycline antibiotics.
Claims4
A preparation method of a high-efficiency visible-light catalytic material, comprising following steps:
- (1) mixing cationic emulsifier and sodium alginate in a solution, followed by ultrasonically dispersing;
- (2) adding AgNO3, Ca(NO3)2 and NaCl into a mixed solution prepared in the step (1) in sequence, followed by stirring, standing, filtering and collecting precipitate;
- and
- (3) adding the precipitate obtained in the step (2) into water, then irradiating with an ultraviolet lamp, filtering, washing and freeze-drying to obtain Ag @AgCl/CA as the high-efficiency visible-light catalytic material;
- wherein the cationic emulsifier is cetyltrimethyl ammonium bromide.
