通过共沉淀法制备催化剂。在老化期间监测前体结构。第一种沉淀物结构为无定形的乔治石，然后转变为未知的晶体结构。通过元素分析、红外光谱和X射线衍射分析，确定了过渡晶型结构为结晶型乔戈里石。前驱体的最终结构为孔雀石。所得Cu/ZnO/Al的Cu表面积
catalysts were prepared by a co-precipitation method. The precursor structures were monitored during the aging. The first precipitate structure was amorphous georgeite, which transformed into the unknown crystal-line structure. The transition crystalline structure was assigned to the crystalline georgeite, which was suggested with elemental analysis, IR and XRD. The final structure of precursors was malachite. The Cu surface area of the resulting Cu/ZnO/Al
