Catalytic material for catalytic activation of persulfate and targeted degradation of typical pollutant in papermaking wastewater and synthesis method and use thereof

A method of preparing a catalyst for degrading phthalates in water, the method comprising:

• dissolving phthalates in acetonitrile in a reactor;
• sequentially adding metal organic framework MIL-88A and methacrylic acid into the reactor and stirring for a first period of time;
• adding tetraethyl orthosilicate and acetic acid into the reactor;
• sealing the reactor;
• heating the reactor at 60-80° C. for a second period of time to form a catalyst containing the phthalates by using the phthalates as template molecules;
• removing the phthalates from the obtained catalyst by extracting to obtain a porous catalyst MIL-88A@MIP;
• and
• drying the porous catalyst MIL-88A@MIP.
