The formation of Ni–Ce–Al composite oxides improved the Ni particle distribution. 4+ 3+ Electron transfer from Ce /Ce facilitated CO methanation at low- temperature. The addition of Ce enhanced the tolerance against carbon deposition at water free condition. ar ti c l e i nf o ab stra ct Article history: Ce-incorporated Ni/c-Al O catalysts, with Ce loadings from 0 wt% to 8 wt%, were prepared by solution 2 3 Received 1 June 2015 combustion method (SCM) and evaluated for CO methanation.
