Abstract
In this work, a novel and simple method was developed to prepare FeNi nanoparticles using konjac glucomannan (KGM) as template. The structure and morphology of the as-prepared nanoparticles were characterized by X-ray diffraction, Fourier transform infrared spectra and scanning electron microscopy. The results showed the KGM template can improve the dispersity and size distribution of the FeNi nanoparticles because it interacted with FeNi and hence formed a complex framework. At the same time, the resultant nanoparticles demonstrated typical ferromagnetic behavior. It is worth of noting that the procedure reported here is green and controllable compared with previous traditional protocols.
