摘要: In this work, we investigated the adsorption performance of IrFe/Al2O3 and Ir/Al2O3 catalysts, which were applied to purify CO in reforming gas [1]. The catalysts were prepared by incipient wetness impregnation method. The results of XRD and TEM both showed that iridium and iron oxide were highly dispersed over the Al2O3. Microcalorimetric measurements of CO and O2 adsorption on IrFe/Al2O3, Ir/Al2O3 and Fe/Al2O3 catalysts were performed using a BT 2.15 heat-flux calorimeter. Microcalorimetry analysis demonstrated that when Ir was supported on the pre-formed Fe/Al2O3, the strength and saturation of CO adsorption on the IrFe/Al2O3 catalyst changed little, respectively. The addition of Fe caused the great enhancement of the strength and saturation uptake of O2 adsorption on the IrFe/Al2O3 catalyst, although the initial adsorption heat of O2 on the IrFe/Al2O3 catalyst was lower than that on the Ir/Al2O3 catalyst. Thus, it was supported that the structure of Fe-promoted Ir/Al2O3 catalyst allowed metallic Ir sites on the surface of catalyst and accessible for CO adsorption, while did not interfere with the O2 adsorption on the FeOx species.
