The catalyst support SiO₂ was firstly pretreated with different amounts of sodium nitrate solution followed by impregnation in copper and zinc nitrates solution.The effects of the preparation method and contents of sodium on the structures and performances of Cu-ZnO/Na-SiO₂ catalysts were investigated.The catalytic activities of these catalysts were evaluated using the dehydrogenation of 2-butanol and the selectivity for methyl ethyl ketone as probes.These catalysts were characterized by means of XRD and TPR.The results indicated that sodium-pretreatment can improve the dispersion of metallic copper and the interaction between the copper species and the support.
