摘要
Syngas production from CO2 reforming of ethanol over an Ir/Ce O2 catalyst was investigated. Catalysts characterization was conducted by X-ray diffraction（XRD）, temperature programmed reduction（TPR）, transmission electron microscopy（TEM） and temperature programmed oxidation（TPO）. The Ir/Ce O2 catalyst was more active and stable toward syngas formation（molar ratio ~1）. The superior catalytic performance was interpreted in terms of the strong interaction between Ir particles and ceria support which was crucial for efficient ethanol/CO2 activation and coke removal on the catalyst surface.
