摘要
The present work describes a procedure for the preparation of iron oxide and carbide nanoparticles in carbon nanotube (CNT) matrix using the wet impregnation method and subsequent heat treatment in different atmosphere. In this way, two specific composites were produced with magnetite and cementite phase particles dispersed in CNTs, respectively, and cementite particles were encapsulated in graphene shells. As-prepared nanoparticles were all single crystalline and characterized by transmission electron microscopy (TEM), high-resolution TEM and X-ray diffraction. The magnetic properties of the resultant products were studied using vibrating sample magnetometer at room temperature. (c) 2007 Elsevier B.V. All rights reserved.
