A highly stable catalyst in methane reforming with carbon dioxide

The nickel catalyst (5% Ni-3% CeO(2)) supported on mesoporous nanocrystalline zirconia with high surface area and pure tetragonal crystallite phase showed high catalytic stability under severe reaction conditions for more than 1500 h on stream. This catalyst showed a stable catalytic structure even after this long period of reaction time. The obtained results revealed that ceria increased the nickel dispersion and had a positive effect in preventing coke formation and increasing catalyst stability. (C) 2009 Acta Materialia Inc.
