Transition metal doping effect and high catalytic activity of CeO2-TiO2 for chlorinated VOCs degradation
文献摘要：
A series of transition metals(Fe,Co,Ni,Cu,Cr and Mn)-doped CeO2-TiO2 catalysts were prepared by the sol-gel method and applied for the catalytic removal of 1,2-dichloroethane(DCE)as a model for chlo-rinated VOCs(CVOCs).The various characterization methods including X-ray diffraction(XRD),N2 adsorption-desorption,UV-Raman,NH3 temperature-programmed desorption(NH3-TPD)and H2 temperature-programmed reduction(H2-TPR)were utilized to investigate the physicochemical properties of the catalysts.The results show that doping Fe,Co,Ni or Mn can obviously promote the activity of CeO2-TiO2 mixed oxides for DCE degradation,which is related to their improved texture properties,acid sites(especially for strong acidity)and low-temperature reducibility.Particularly,CeTi-Fe doped with moderate Fe exhibits excellent activity for 1,2-dichloroethane(DCE)degradation,giv-ing a T90％value as low as 250℃.More importantly,only trace chlorinated byproducts were produced during the low-temperature degradation of various CVOCs(dichloromethane(DCM),trichloroethylene(TCE)and chlorobenzene(CB))over CeTi-Fe1/9 catalyst with high durability.
