With the help of nanotechnology, a kind of Pt/Fe bimetallic nanoparticles with different ratio of n_Pt/n_Fe was prepared with PVP as protective agent and ethylene glycol as the reducing agent. And then the desired Pt-FeO_x catalysts with different microstructural environment were obtained by following oxidation treatment and used as catalysts for CO oxidation. The results show that the number of FeO_x species affects both the valence of Pt species and the redox properties of Fe species themselves. These properties have a direct and indirect effect on the activation of CO and oxygen molecules. It can be concluded that the presence of appropriate FeO_x species around Pt is beneficial to the construction of highly active CO oxidation catalysts.
