摘　　要：稀土元素对钯催化剂的修饰能够极大地促进丙烯腈选择性气相加氢制丙腈的活性和稳定性。作者主要讨论了掺杂的镧系元素的促进效应。The modification of rare earth elements to palladium catalysts leaded to great promotion on both the activity and stability in selective gas hydrogenation of acrylonitrile to propionitrile. The promotion effect of lanthanide-dopant was briefly discussed.
