     the clsingle bondtio2 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.
