CO removal was enhanced slightly and presented at lower reaction temperatures following promotion of CeO2 on Ni. The enhanced ability to reduce CO was mainly a result of methanation rather than WGS during a CO removal reaction. Based on X-ray diffraction and temperature-programmed reduction, CeO2 appeared to change the Ni surface properties. Because the bond strength between C and O atoms in CO was weakened by the surface oxygen of CeO2 on Ni, the CeO2-promoted Ni catalyst showed higher CO conversion and lower selectivity to WGS than Ni bulk catalyst.
