Preparation and characterization of a novel heteronanostructure of zirconium diboride nanoparticlecoated multi-walled carbon nanotubes

چکیده مقاله

A zirconium diboride/carbon nanotube (CNT@ZrB2) hetero-nanostructure was synthesized using a onestep strategy by a carbothermal reduction reaction. During this process ZrO2 was reduced to ZrB2 and ultrafine nanoparticles with a size of 40 nm were uniformly coated on the nanotubes. The chemical composition, morphology and phase structure of the sample were investigated using techniques such as XRD, FTIR, TGA, FESEM, TEM and Raman spectroscopy. The results showed the surprising thermal stability of the CNT@ZrB2 compared to CNT. This improved thermal performance is closely related to the synergistic effect of ZrB2 on CNT.
