摘要
The effect of K addition on Au/Activated carbon (AC) catalyst for CO selective oxidation in hydrogen-rich gas was investigated in this paper. It was found that K addition resulted in activity promotion for selective CO oxidation. The results of XRD and XPS characterization indicated that K addition produced the highly dispersed Au species and retarded the sintering of Au species on the catalyst surface during the reaction.
