石墨包覆纳米镍颗粒的结构及磁性能的表征
Synthesis, morphology and magnetic properties of graphite-encapsulated nickel nanoparticles
摘要
Abstract
Aimed at synthesizing the encapsulation of nickel nanocrystal within graphitic carbon, effective experiments were carried out by adjusting the mole ratio of carbon source and metal source in these precursors. The chemical composition, nanostructures and magnetic properties of the composite particles were analyzed by using X-ray diffraction (XRD) , transmission electron microscopy (TEM), energy dispersive X-ray detector (EDX) and vibrating sample magnetometer (VSM). The results showed that the different size and spherical graphite-encapsulated nickel nanoparticles with a perfect core-shell structure had been prepared and that these magnetic composite particles mainly distributed in 10-55 nm. The magnetic measurements demonstrated that the as-prepared CENNPs took on super-paramagnetic or ferromagnetic behaviors at room temperature.关键词
