The invention relates to a composite photocatalytic material and a preparation method and application thereof. The preparation method comprises the following steps: (1) uniformly mixing cobalt nitrate hexahydrate, melamine and deionized water under ultrasonication; The solution is dried; (3) the solid obtained after drying is ground and calcined to obtain solid powder Co-g-C 3 N 4 ; (4) solution A and solution B are uniformly mixed, and Co-g-C 3 is added N 4 , continue to sonicate to obtain a uniformly dispersed mixed solution; (5) hydrothermally react the mixed solution; (6) centrifuge, wash, dry, cool and grind the reacted material to obtain Co-g- C 3 N 4 /BiOCl composite photocatalytic material. Compared with the prior art, the present invention has the advantages of simple preparation method, convenient operation, and can effectively degrade rhodamine B under visible light. |
