Abstract:
Chromium oxide/carbon nanocomposites (COCNC) were synthesized by using a liquid phase plasma process, and the electrical properties of the supercapacitor electrode were investigated. Spherical chromium oxide (Cr₂O₃) nanoparticles with the size of 100-150 nm were dispersed uniformly on activated carbon powder surface. The quantity of chromium oxide nanoparticle precipitate increased with increasing LPP reaction time and the specific capacitance of COCNC increased with increasing LPP reaction time.
