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.
The graphene oxide was functionalized by diphenylphosphine through covalent bond. The functionalized 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.
