摘要:

将二苯基膦通过共价键引入到氧化石墨烯(GO)中, 利用二苯基膦对Pd的鳌合配位作用, 合成了GO固载Pd催化剂(GO-P-Pd); 通过红外光谱、 X射线衍射和X射线光电子能谱等手段对催化剂进行了表征, 并考察了其对Heck偶联反应的催化性能. 结果表明, 该催化剂表现出优异的催化性能, 重复使用7次后催化活性无显著降低, 并且对不同的反应底物有较好的普适性.

关键词: 氧化石墨烯, Heck偶联反应,

Abstract:

The graphene oxide was functionalized by diphenylphosphine through covalent bond. The functio-nalized graphene oxide was used to immobilize palladium via the coordination bonds between the diphenylphosphine and palladium. The as-synthesized catalyst(GO-P-Pd) was characterized by Fourier transform infrared spectroscopy(FTIR), X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS) and applied in the Heck coupling reaction. The result shows that GO-P-Pd exhibits excellent catalytic performance with high activity and stability. And the catalyst can also be applied to catalyze a wide scope of substrates.

Key words: Graphene oxide, Heck coupling reaction, Pd(Ed.: V, Z, K)
