英文摘要a novel bifunctional catalyst irfeox/sio2, which was very active and selective for preferential oxidation of co under h-2-rich atmosphere, was developed in this study. xrd, h-2-tpr, and chemisorption were applied to characterize three kinds of irfeox/sio2 catalysts prepared by different impregnation sequences. the results indicated that both feox and jr species were highly dispersed on the sio2 support; the reduction of ir species in the fe-promoted ir/sio2 catalyst became easier than those in the ir/sio2, together with the partial reduction of fe2o3; the saturation uptake of o-2 adsorption was greatly enhanced. in-situ drifts, xps, and mossbauer techniques were further applied to detect the structural information on the selected ir-feox/sio2 catalyst prepared by co-impregnation method. a non-competitive adsorption catalytic mechanism was proposed where co adsorbed on it sites and o-2 adsorbed on feox sites; the reaction probably took place at the interface of ir and feox or via a spill-over process.
