Atmospheric pressure barrier discharge at high temperature: Diagnostics and carbon nanotubes deposition

Popis výsledku v původním jazyce

Atmospheric pressure dielectric barrier discharge (DBD) in Ar/H-2 gas feed with C2H2 or CH4 admixture was studied at room and high temperature of 680 degrees C by plasma diagnostics (electrical measurements, fast camera imaging, and optical emission spectroscopy). It was shown that filamentary DBD in pure Ar or Ar/H-2 can be converted into homogeneous discharge by an acetylene admixture. Fast intensified charge-coupled device (ICCD) camera proved that this homogeneous discharge is an atmospheric pressure glow discharge (APGD) at room temperature whereas at high temperature the discharge mode switches at every half-period between APGD and atmospheric pressure Townsend discharge. The high temperature discharges (610-710 degrees C) in Ar/H-2/C2H2 and Ar/H-2/CH4 were also investigated with respect to a surface bound deposition of carbon nanotubes using 5 nm thick iron layer as a catalyst. CNTs were deposited without any dedicated catalyst pretreatment phase.
