Photocatalytic degradation of ethyl paraben wastewater by mixed crystal molecularly imprinted TiO2
Using ethyl paraben as the template molecule and n-tetrabutyl titanate as the titanium source, the molecularly imprinted titanium dioxide (MIP-TiO2) photocatalyst was prepared by the sol-gel method. The effects of different pH values, imprinting molecular weights and other factors on the degradation...

| description | Using ethyl paraben as the template molecule and n-tetrabutyl titanate as the titanium source, the molecularly imprinted titanium dioxide (MIP-TiO2) photocatalyst was prepared by the sol-gel method. The effects of different pH values, imprinting molecular weights and other factors on the degradation of ethyl paraben were studied, and the materials were analyzed by TEM, XRD, FT-IR and other characterization methods. The results show that the catalyst has a mixed crystal structure in which anatase and rutile ore coexist, and the rutile ore content of MIP-TiO2 is calculated to be 78.5%. Catalytic degradation of ethyl paraben by reacting for 40 min under ultraviolet light, the removal rate of ethyl paraben by pure TiO2 is 80.74%, and the removal rate of ethyl paraben by MIP-TiO2 can reach 96.27%. MIP-TiO2 is 15.53% higher than TiO2. MIP-TiO2 has imprinting holes, which can target the target pollutants and effectively improve the selectivity of the photocatalyst MIP-TiO2. The selectivity factor of MIP-TiO2 is 1.69 times that of TiO2. |
