Syngas production from CO2 reforming of ethanol over an Ir/CeO2 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/CeO2 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.
