金属铜纳米颗粒在氮掺杂碳纳米管上得到了有效的分散和稳定。它们的直径约为8-10 nm，对体相氧化具有高度的抗性。在合成炔丙胺的A（3）型偶联反应中考察了它们的催化活性和可循环性。这是很容易的，可以制备非对映异构体纯的脯氨酸衍生物，并有效地回收和重复使用的负载催化剂几次。(c)2012 Elsevier B. V.保留所有权利。
Metallic copper nanoparticles have been efficiently dispersed and stabilized on nitrogen-doped carbon nanotubes. They are about 8-10 nm in diameter and highly resistant against bulk oxidation. Their catalytic activity and recyclability have been investigated in A(3)-type coupling reactions for the synthesis of propargylamines. It was easily possible to prepare diastereomerically pure derivatives of proline and to efficiently recover and reuse the supported catalyst several times. (c) 2012 Elsevier B.V. All rights reserved.
