　　Ceria based oxides has emerged as promising materials for thermochemical CO production from CO2 due to the lower reduction temperature and higher CO production than those of pure CeO2 as well as transition metal oxides(such as FeOx).Here we explore the two-step thermochemical cycles for CO2 reduction using Ce0.5Zr0.5Ox,Pr0.1Ce0.45Zr0.45Ox-co(coprecipitated Pr)and Pr0.1Ce0.45Zr0.45Ox-im(impregnated Pr).The obtained calcined powders were analyzed by X-ray diffraction,BET specific surface area,X-ray photoelectron spectroscopy(XPS),Raman spectroscopy and transmission electron microscopy(TEM).
