Ni/SiO2 and Ni-Al2O3/SiO2 catalysts were prepared by incipient wetness impregnation using citrate and nitrate precursors and tested with a reaction of combination of CO2 reforming and partial oxidation of methane to produce syngas (H-2/CO). The catalytic activity of Ni/SiO2 and Ni-Al2O3/SiO2 greatly depended on interaction between NiO and support. NiO strongly interacted with support formed small nickel particles (about 4 nm for NiSC which is abbreviation of Ni/SiO2 prepared with Nickel citrate precursor) after reduction. The small nickel particles over NiSC catalysts exhibited a good catalytic performance. Crown Copyright (C) 2008 Published by Elsevier Ltd on behalf of international Association for Hydrogen Energy.
