Yttrium-doped NiO-ZrO m catalyst was found to be novel for carbon resistance in the CO 2 reforming of methane. Yttrium-free and -doped NiO-ZrO m catalysts were prepared by a one-step urea hydrolysis method and characterized by Brunauer-Emmett-Teller (BET), TPR-H 2 , CO 2 -TPD, XRD, TEM and XPS. Yttrium-doped NiO-ZrO m catalyst resulted in higher interaction between Ni and ZrO m , higher distribution of weak and medium basic sites, and smaller Ni crystallite size, as compared to the Y-free NiO-ZrO m catalyst after reaction. The DRM catalytic tests were conducted at 700 • C for 8 h, leading to a significant decrease of activity and selectivity for the yttrium-doped NiO-ZrO m catalyst. The carbon deposition after the DRM reaction on yttrium-doped NiO-ZrO m catalyst was lower than on yttrium-free NiO-ZrO m catalyst, which indicated that yttrium could promote the inhibition of carbon deposition during the DRM process.
