摘要：
The objective of this work is to synthesize pure stoichiometric titanium carbide and stoichiometric titanium carbide/hydride core-shell nanoparticles using the Guen-Miller Flow-Levitation method. The nanoparticulate are obtained via chemical reaction between nascent titanium nanoparticles and tailored gaseous hydrocarbons. Characterization of the nanoparticles is performed using analytical techniques including transmission electron microscopy, electron and X-ray diffraction, X-ray photoelectron spectroscopy, elemental analysis and specific surface area analysis. The results confirm the single-crystal nature and purity of the titanium carbide nanoparticles and demonstrate the coherence of single crystal titanium carbide core and titanium hydride shell in the TiC/TiH2 core-shell nanoparticles.
