Oxidation Activity

Fe–Cu bimetal nanoparticles were prepared by the dual-mode arc-plasma process. The CO oxidation activity of Fe–Cu/CeO2 was enhanced by thermal aging at 900 °C. CO oxidation over aged Fe–Cu/CeO2 proceeded via the Mars–van Krevelen mechanism.

Oxidation Activity

High CO oxidation activity of Pd/CeO2 as prepared by using an arc-plasma process was lost by thermal ageing at 600 °C in air, whereas further ageing at 900 °C enhanced significantly the activity, exceeding that of the as-prepared catalyst.
