1. 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.
