Ni-Sm/SiC catalysts prepared by hydrothermal method for carbon dioxide reforming of methane

Ni-Sm/SiC (Ni: 9%, Sm: 5%) catalysts were prepared by a hydrothermal route for carbon dioxide reforming of methane. The catalysts were characterized by XRD, BET, ICP, H2-TPR, TG-DTA and TEM. The catalytic performance, influence of different nickel precursors and carbon deposition in the CO2 reforming of CH4 were investigated. The results suggested that the Ni-Sm/SiC catalysts prepared by a hydrothermal route showed excellent catalytic activity, stability and good coke resistance. Different nickel precursors nearly had no impact on the performance of the catalysts.
