| 研究開始時の研究の概要 |
We synthesize nanoparticle of metal nitrides for future energy application. We aim to understand the effects of the RF thermal plasma parameters on the formation of nanoparticle HEMN via a combination of experiments and numerical calculation to optimize the materials and the synthesis process.
|
| 研究実績の概要 |
Plasma emission spectrum was measured, and the plasma temperature was estimated. Pure metal powders of Ti, Cr, V, and Fe was used for synthesis of TiN, CrN, and FeN nanoparticles, respectively. The parameters were optimized for synthesis of the metal nitride nanoparticles with cubic NaCl structure. The electrochemical properties of the nanoparticles were evaluated. The samples of CrN and FeN showed excellent catalyst properties comparable with that of Pt.

3: やや遅れている
理由
The power of the RF thermal plasma system was only 6 kW. Low plasma power makes it difficult to optimize the feeding rate for fully vaporization of refractory nitride powders like TiN or AlN
|
| 今後の研究の推進方策 |
The research aim is to synthesis high entropy nitride nanoparticles from the mixture of pure metal powders. The approach was chosen to overcome the difficulty in achieving full vaporization of refractory nitride as raw powder for the current 6 kW RF thermal plasma system. The raw metal powders are mixed by using planetary ball milling. RF thermal plasma is used for synthesis of the nanoparticles from the mixture of powders. Crystal structure, quantity, and size of the synthesized nanoparticles will be quantitatively analyzed by XRD, SAXS, and SEM/TEM.
Electrochemical properties of the high entropy nitride nanoparticles will be evaluated.
