In this paper, we report a simple method to synthesize LiFePO4/carbon-network composite using the reproducible, natural sawdust as carbon precursor and Fe2O3 as Fe-source.The phase purity of the composite was examined by X-ray diffraction, and powder morphology was observed by TEM. The composites were composed of spherical particle and amorphous network structure.
Fe 3 O 4 magnetic nanoparticles (NPs) were synthesized by the co-precipitation of Fe 3+ and Fe 2+ with ammonium hydroxide under hydrazine hydrate, and were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). In order to improve the particle dispersion, the bare Fe 3 O 4 magnetic...
