Cu-Fe-MOFs catalyst for activating PMS to degrade ciprofloxacin as well as preparation method and application of Cu-Fe-MOFs catalyst

The invention provides a Cu-Fe-MOFs catalyst for activating PMS to degrade ciprofloxacin as well as a preparation method and application of the Cu-Fe-MOFs catalyst, and belongs to the technical field of environmental pollution treatment. The preparation method comprises the following steps: mixing iron salt, copper salt, an organic ligand and an organic solvent, and carrying out solvothermal reaction to obtain a precursor; the organic ligand is trimesic acid; and the precursor is subjected to thermal activation, and the Cu-Fe-MOFs catalyst is obtained. According to the method, Cu and Fe are doped into MOFs, Cu-Fe-MOFs prepared through solvothermal and thermal activation have the pore structure of an original MOFs material, active sites can be increased, the Cu-Fe-MOFs can exist in water more stably, recycling is facilitated, waste is reduced, and the problems that an existing catalyst material is few in active sites, insufficient in water stability, low in energy consumption and prone to secondary pollution a
