“…Nickel-containing catalysts are widely used in industry and show valuable properties in several laboratory-scale reactions, e.g., selective catalytic reduction of nitrogen oxides with methane, direct cracking of methane, ethylene dimerization, and CO hydrogenization In most cases nickel is used in catalysis in the metallic state, and the particle size appears to be the most important parameter affecting the activity and selectivity . However, in a number of reactions (e.g., selective catalytic reduction of nitrogen oxides) nickel operates in a cationic state .…”

“…The number of surface nickel atoms was frequently estimated by the uptake of H 2 , , while the numbers of surface Pd and Ru atoms were estimated by the uptakes of H 2 and CO, assuming the stoichiometric ratios of Pd/H = 1, Pd/CO = 2, Ru/H = 1, and Ru/CO = 1. , However, these methods are questionable owing to the presences of hydrogen spillover on Ru and absorption on Pd, , and the M/CO ratios may be different at different conditions. , Thus, we measured the uptakes of H 2 for the Pd/CMC and Ni/CMC at different hydrogen pressures.…”
