A study was carried out on the effect of Co, Ce, and La oxides as modifying additives on the activity of an NiO/\( \gamma \)-Al2O3 catalyst in the partial oxidation of methane. The introduction of cerium and lanthanum oxides enhances the resistance of the catalyst to coking. The increase in the activity of the lanthanum-modified catalyst is related to a lower temperature required for its reduction and increased dispersion of the metallic nickel particles.
