Abstract

Cobalt nitride as a new type of O₂ activator was used to modify Pt-based catalyst for catalytic oxidation. The nitrided Co/Pt/γ-Al₂O₃ catalyst system was highly efficient for preferential CO oxidation in excess H₂ at low temperatures, which was attributed to a noncompetitive dual-site reaction pathway.
