Abstract
▶ 5 wt% Ni based CexZr1−xO2 with C/Z mass ratios ranging from 4 to 0.25 and Ru or Rh promoted Ce0.72Zr0.28O2 catalysts were successfully synthesized. ▶ C/Z and noble metal addition effects were evaluated on catalyst structural properties and catalytic activity in CO2 methanation reaction. ▶ Impressive CO2 conversion and extremely high selectivity to methane (superior to 98%). ▶ Both incorporated Ni2+/Ni0 ratio optimization and noble metal addition boosted the catalyst performance. ▶ 5Ni(60-40) appeared to be the best catalytic system.
