The invention "a method for degrading tetracycline" belongs to the technical field of organic wastewater treatment. The method adopts nitrogen-doped carbon quantum dot-carbon nitride metal-free catalyst to activate persulfate to degrade tetracycline under visible light. The nitrogen-doped carbon quantum dot-carbon nitride metal-free catalyst uses carbon nitride as a carrier, and the carbon nitride is decorated with nitrogen-doped carbon quantum dots. The metal-free catalyst of the invention has the advantages of strong light absorption ability, high photo-generated electron-hole separation efficiency, high catalytic activity, strong redox ability and the like. Using the catalyst to activate persulfate to degrade antibiotic wastewater under visible light can catalyze persulfate to efficiently generate strong oxidative free radicals, and has the advantages of high degradation efficiency, good reusability, no secondary pollution and wide application. , has a very good practical application prospect. |
