A Novel Method for Synthesis of Homogeneous Carbon Encapsulated Fe Nanoparticles Based on Natural Biopolymer

摘要：

A novel and efficient route for preparing carbon encapsulated metal nanomaterials using staple biopolymer-starch as the carbon precursor was presented. Fe particles can be effectively encapsulated inside carbon shells by carbonizing composite of starch and iron oxide under hydrogen in a controllable way. Transmission electron microscopy (TEM), energy dispersive X-ray (EDX) and X-ray diffraction (XRD) were employed to characterize carbon encapsulated nanomaterials. The α-Fe and γ-Fe phases were clearly identified in those carbon encapsulated nanoparticles. The growth mechanism of carbon encapsulated metal nanoparticles was briefly discussed.
