碳包覆铁铜合金纳米粒子的制备及其表征
Preparation and characterization of carbon encapsulated FeCu alloy nanoparticles
摘要
Abstract
In this paper, carbon encapsulated FeCu alloy nanoparticles were prepared by using sucrose as carbon source and using ferric nitrate, copper nitrate as metal sources, through reducing liquid phase and annealing at high temperature. The samples with different mole ratio of Fe/Cu were studied by XRD. The results showed the phase of the sample with mole ratio of K4 was pure. In addition, the as - prepared sample with mole ratio of 1: 4 was characterized by EDS, TEM and Raman. The result indicated that the sample was core/shell structure: the metal core consists of FeCu alloy (the average size was 43 nm), the carbon shell was amorphous carbon with the thickness about 5 nm.关键词
