The invention relates to the technical field of functional materials and advanced oxidation, and discloses a preparation method of a CeO 2 /Co 3 O 4 photocatalyst for activating potassium hydrogen persulfate composite salt driven by visible light, comprising the following steps: 1), 2) , 3). The preparation method of the CeO 2 /Co 3 O 4 photocatalyst activated with potassium hydrogen persulfate composite salt driven by visible light has the advantages of green environmental protection, simple preparation process, controllable reaction conditions and low cost, etc., and the cobalt tetroxide The modified ceria p-n heterojunction photocatalyst is mixed with the initial ciprofloxacin solution, and then an appropriate amount of PMS is added to carry out photocatalytic reaction under light conditions to achieve effective degradation of ciprofloxacin, which can effectively avoid ciprofloxacin It is difficult to remove floxacin from the water body, which effectively solves the problems of long catalysis time for ciprofloxacin, large amount of reagents, low separation efficiency of photogenerated carriers and poor stability. |
