Effects of boron-doping on the morphology and magnetic property of carbon nanotubes

摘要

Boron carbide nanotubes (nano-fibers) was prepared by B powder and carbon nanotubes (CNTs) at high temperature in a vacuumed quartz tube.The morphology,microstructure,component and magnetic property of samples were characterized by transmission electron microscopy (TEM),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS)and magnetic property measurement system (MPMS) controller.The results showed that B-doping CNTs have great difference in the morphology and magnetic property from those of pristine CNTs.
