Novel cobalt nitride-induced oxygen activation on Pt-based catalyst for catalytic oxidation

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.
