Abstract

Core-shell TaNx nanocomposites were prepared through the in-situ coating process on the basis of synthesis of TaN 0.5 nanoparticles. The X-ray diffraction results showed the nanocomposites consisted of TaN and TaN 0.5 crystalline phase. TEM and SEM images demonstrated that TaN nanopowders as a coating layer grew on the surface of TaN 0.5 nanoparticles, producing TaNx nanocomposites with core-shell structure. The specific surface area of nanocomposite powders was as large as 4.87 m 2g -1-6.13 m 2g -1, indicating that such TaNx nanocomposites exhibited great potential of application to the capacitor with ultra high specific capacitance.
