A series of supported copper based catalysts for the coupling process of 2-butanol dehydrogenation and furfural hydrogenation were prepared by different methods.The effect of promoters and silicon sources on the catalysts' activities were emphatically investigated.The results showed that the CMS-Ce catalyst supported on the self-prepared hollow silica had the best activity.The conversion of furfural and the selectivity to furfuryl alcohol both reached 100%,while the conversion of 2-butanol reached 52.9% and the selectivity to methyl ethyl ketone was 100% under the optimized reaction conditions.Cu0 was believed to be the active site of the catalysts based on XRD and TPR characterization.
