摘要
The effect of the support nature and metal dispersion on the performance of Pt catalysts during steam reforming of ethanol was studied. H-2 and CO production was facilitated over Pt/CeO2 and Pt/CeZrO2, whereas the acetaldehyde and ethene formation was favored on Pt/ZrO2. According to the reaction mechanism, determined by temperature-programmed desorption (TPD) and Diffuse Reflectance Infrared Spectroscopy (DRIFTS) analysis, some reaction pathways are favored depending on the Support nature, which can explain the differences observed oil the resulting product distribution.
