Nickel supported on reduced graphene oxide was synthesized by chemical vapor deposition technique. The crystal structure and magnetic properties of the prepared sample were studied by means of Raman spectrometry, X‐ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), inductively coupled plasma optical emission spectrometry (ICP‐OES), and vibrating sample magnetometry (VSM). The result of Raman spectroscopy revealed the structure of few‐layer graphene as the support for Ni nanoparticles. XP spectrum confirmed the presence of metallic Ni on the a few‐layer graphene surface. TE micrograph showed that the nickel nanoparticles were sphere shaped and the mean particle size is about 20 nm deposited on the reduced graphene oxide. The magnetic study showed the ferromagnetic behavior of 3.2 wt% nickel over reduced graphene oxide at room temperature.

化学气相沉积法制备的氧化石墨烯负载镍的磁性和结构研究

通过化学气相沉积技术合成了负载在还原氧化石墨烯上的镍。通过拉曼光谱，X射线光电子能谱（XPS），透射电子显微镜（TEM），电感耦合等离子体发射光谱（ICP-OES）和振动样品磁强度法研究了所制备样品的晶体结构和磁性能。 （VSM）。拉曼光谱法的结果表明，多层石墨烯的结构可作为Ni纳米粒子的载体。XP光谱证实了在几层石墨烯表面上存在金属Ni。TE显微照片表明，镍纳米颗粒是球形的，平均粒径约为20 nm，沉积在还原的氧化石墨烯上。磁性研究表明3的铁磁行为。
