高效催化Suzuki偶联反应的催化剂——石墨烯负载纳米Pd-Cu合金纳米复合材料

A Highly Active Catalyst for Suzuki Cross-Coupling Reactions —Pd-Cu Bimetallic Nanoparticles Supported on Graphene Nanocomposites

设计了石墨烯(G)负载的纳米Pd-Cu合金(Pd-Cu/G)催化剂的制备路线。对Pd-Cu/G催化剂进行了XRD、XPS、TEM的表征,并对结果进行了分析和讨论。为了进一步探索Pd-Cu/G催化剂的催化活性,将催化剂在非均相条件下应用于Suzuki偶联反应。相比于传统均相催化剂,Pd-Cu/G不仅具有更好的催化效果还可以实现催化剂的循环使用,具有潜在的应用价值。

Graphene supported Pd-Cu bimetallic nanoparticle (Pd-Cu/G) as a highly active catalyst was prepared. The composition of resulting Pd-Cu material was analyzed and discussed with the characterization of X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy. Compared with the traditional homogeneous catalysts, the as-prepared Pd-Cu/G not only exerted satisfied catalytic activity but also revealed recycle stability, which has a wide range of applications.
