CO 2 reforming of methane was performed over two series of modified Ni/ZrO 2 catalysts having high nickel contents. One is the modification of zirconia with lanthanum‐, cerium‐ or manganese‐oxide. Among them, Ni/La–ZrO 2 exhibited the highest activity and good stability, whereas Ni/Ce–ZrO 2 and Ni/Mn–ZrO 2 gave low carbon formation during the reaction. The other modified catalysts were prepared by adding basic oxides to the nickel side. Ni–Mg/ZrO 2 exhibited the best activity and stability, wherein a magnesium promoter is attributed to increasing the dispersion of nickel and enhancing the interaction between CO 2 and the catalyst during the CO 2 reforming.
