Abstract

Iron oxides nanoclusters were synthesized using Pluronic P123 and edetic acid as coordination agents, and its catalytic oxidation of CO to CO₂ with or without hydrogen were investigated. The crystalline pattern structure and morphology of iron oxide nanocluster was characterized by XRD and SEM, respectively. The result indicated that the crystalline of iron oxide and H₂ promoting effect determined the CO catalytic oxidation activity. The γ-Fe₂O₃ showed less catalytic activity for CO oxidation without H₂ and the highest CO conversion was 80% at 500 °C; but it displayed higher activity for CO in H₂ stream and 100% CO conversion could be achieved at 220 °C.
