The CeO₂-TiO₂ sol-gel was prepared by the sol-gel method using polyvinylpyrrolidone(PVP) sol/titaniumn-butyloxide (Ti(OC₄H₉)₄) as the precursor and Ce(NO₃)₃·6H₂O as the doping agent,and the CeO₂ doped TiO₂ nanofiber was prepared by the electrospinning technique. Finally,a layer of carbon membrane was deposited on the surface of the CeO₂-TiO₂ composite nanofibers using chemical vapor deposition(CVD). The structure and properties of the carbon-coated nanofibers were studied using SEM,FTIR,TEM,XRD,and its photocatalytic activity toward the degradation of ciprofloxacin hydrochloride was investigated under UV-light irradiation. The experimental results show that carbon-coated TiO₂ composite nanofibers exhibit higher photocatalytic performance. When the irradiation time is 40 min,the degradation rate of ciprofloxacin hydrochloride is up to 85.8%.
