Effect of Support on Catalytic Performance of Au Catalyst for Partial Oxidation of Ethanol to Generate Hydrogen

WANG Yue,ZHANG Kai-lin,ZHUO Ou,LI Ning (College of Chemical and Biological Engineering,Guilin University of Technology,Guilin,Guangxi,541004,China)  
A series of Au catalysts supported on Al2O3,ZnO,CeO2 and Fe2O3 were prepared by co-precipitation method,and the crystalline structure,surface reduction and adsorption properties of the catalysts were characterized by XRD,H2-TPR and H2-TPD techniques.At the same time,the catalytic activity and selectivity were investigated.The results showed that the supports had a great impact on Au catalysts.For the Au catalyst loaded on CeO2,the active component Au and the CeO2carrier could form a strong interaction and there were more oxygen species on the surface of the catalyst.The Au/ CeO2 catalyst revealed more excellent activity and selectivity for producing hydrogen from ethanol partial oxidation.When the reaction temperature was 450℃,the ethanol conversion rate and H2selectivity reached 96.0% and 86.3%.
