Microwave-assisted synthesis of selective degradation photocatalyst by surface molecular imprinting method for the degradation of tetracycline onto ClTiO2
چکیده انگلیسی

The ClTiO2 imprinted photocatalyst was prepared via surface molecular imprinted technology with a facile microwave-assisted method with tetracycline (TC) as the molecular template. 4-vinyl pyridine (4-vp), trimethylolpropane acrylate (TMPTA), and 2,2-azobisisobutyronitrile (AIBN) were considered to functional monomer, cross-linking agent and initiate, respectively. The sample was characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), UV–vis diffuse reflectance spectra (UV–vis DRS), fourier transform infrared (FT-IR), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Comparing with the non-imprinted photocatalyst, the molecular imprinted photocatalyst exhibited higher photo-degradation rate for TC but also showed to enhance selective activity for target molecular. The degradation rate of TC was 72.35% within 60 min under visible irradiation.


► A new molecular imprinted photocatalyst was synthesized by microwave-assisted method.
► The MIP photocatalyst played the highest photocatalytic activity and selectivity.
► The effects of various factors on the degradation behavior were investigated.
► The first-kinetic and second-kinetic of photocatalytic degradation were studied.
