Abstract :
A new type of nanocomposite particles are produced by an active plasma-metal reaction method. Co-TiN nanocomposite particle with dumbbell-like morphology shows good thermal stability. Hydrogen desorption characteristics are examined by temperature-programmed desorption experiments. Hydrogen desorption is observed at 380–600 K. The effect of CO coadsorption on the hydrogen desorption is examined and no significant effect is observed for the Co-TiN nanocomposite particle. The results are compared with those of Ni-TiN nanocomposite particle.
