本文研究了急冷Ｃｕ_（３０）Ａｌ_（７０）合金及其制成的急冷骨架铜催化剂，并与工业上广泛应用的Ｃｕ_（３０）Ａｌ_（７０）合金催化剂进行了对比．结果表明：急冷Ｃｕ_（３０）Ａｌ_（７０）合金组织较均匀，单质Ａｌ相较少，Ｃｕ，Ａｌ元素分布均匀．急冷骨架铜催化剂比表面积较小，孔径大，孔容积较大．急冷骨架铜催化剂在木糖加氢反应中的催化活性高于普通的骨架铜催化剂．
The structures of rapidly solidified Cu_(30)Al_(70) alloy compared with conventional Cu_(30)Al_(70) alloy have been investigated. The structure in the rapidly solidified Cu_(30)Al_(70) alloy is more homogeneous than that of the conventional one and the aluminum phase is in the minor. The Al and Cu elements is also homogeneously distributed in the rapidly solidified Cu_(30)Al_(70) alloy. The rapidly solidified Raney copper has a smaller specific surface area and larger pore volume and diameter. The catalytic activity of rapidly solidified Raney copper is superior to that of the conventional Raney copper in hydrogenation.Correspondent: SUN Li, (State Key Laboratory of RSA, Institute of Metal Research, Chinese Academy of Sciences, Shengyang 110015)
