<正> RE-doped Ni-based catalysts were prepared by sol-gel method. These catalysts were applied to the reaction of CO2 reforming CH4 to syngas. The studies reveal that RE-doped (RE = La, Ce, Sm, Yb) Ni-based catalysts show higher catalytic activity than undoped Ni-based catalyst, and with the increasing of RE-doped quantity, the catalytic activity of catalysts exhibits regular changes. When RE-doped quantity is 0. 2% (molar ratio), the catalysts show the best catalytic activity.
