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

研究目的是了解等离子体参数对金属氮纳米粒子合成的影响。以TiN和/或Cr2N粉末为原料，采用射频热等离子体法制备了TiN、CrN和TiCrN纳米颗粒。成功地优化了等离子体参数，用于合成TiN或CrN等二元氮化物纳米颗粒。在混合TiN和Cr2N粉末合成TiCrN纳米颗粒时，等离子体合成后存在大量残留的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.
