Abstract
AbstractIn this work, we present and characterize a microwave plasma microtorch that can support the formation of diamond nanoparticles (DNPs) in the gas phase when using hydrogen‐methane as a precursor gas. We first showed how the nonequilibrium character of the plasma obtained in this microtorch ensures enhanced H‐atom, , and production at moderate gas temperature levels that provides thermal stability of DNPs. The material characterization by TEM, Raman, and electron energy loss spectroscopy spectra confirm the presence of a substantial amount of diamond phase in the carbon dust particles collected from the plasma phase. Investigation of the effects of injected microwave power on the process characteristics showed a direct correlation between enhanced production and the appearance of the diamond phase, which points out the critical role of as far as gas‐phase nucleation of DNPs is concerned.
