Fabrication and Application of Magnetite Coated N-doped Carbon Microtubes Hybrid Nanomaterials with Sandwich Structures

Abstract

In this work, the N-doped carbon microtubes have been synthesized by using MoO3 microrods as the sacrifical template. Then, the Fe3O4 nanoparticles were integrated into the N-doped carbon microtubes to get the triple-walled Fe3O4@N-doped carbon@Fe3O4 microtubes via a high temperature decomposition process. Owing to the coordination ability of the nitrogen and unique structures for the N-doped carbon microtubes, the Fe3O4 nanoparticles were closely attached to both the external and internal surfaces of N-doped carbon microtubes, thus assured a relatively good response to the external magnetic field. All these features make the nanocomposites well fitted for adsorption, catalysis, energy storage etc. Moreover, the N-doped carbon microtubes can be used as versatile templates to synthesize other triple-walled composites M@N-doped carbon@M microtubes such as (M = Cu(Cu2O), MnO2, MoS2), which greatly widen the application of N-doped carbon microtubes.
