New method for preparation of nanoparticles of high entropy metal nitrides for future energy applications

研究了等离子体参数对金属氮化物纳米粒子合成的影响。采用射频热等离子体技术，以TiN和/或Cr 2N粉末为原料，合成了TiN、CrN和TiCrN纳米颗粒。等离子体参数被成功地优化用于合成二元氮化物纳米颗粒，例如TiN或CrN。当将TiN和Cr 2N粉末混合用于合成TiCrN纳米颗粒时，在等离子体合成之后存在大量残余TiN和金属Cr纳米颗粒。

The research aim was to understanding the effect of plasma parameters on the synthesis of metal nitride nano particles. Radio-frequency thermal plasma was used to synthesis of TiN, CrN and TiCrN nanoparticles from the powders of TiN and/or Cr2N. The plasma parameters were successfully optimized for synthesis of binary nitride nanoparticles, e.g. TiN or CrN. When mixing TiN and Cr2N powders for synthesis of TiCrN nanoparticles, a large amount of residual TiN and metal Cr nanopaticles present after plasma synthesis.
