Iron oxide/carbon composite was synthesized using a liquid phase plasma process to be used as the electrode of supercapacitor. Spherical iron oxide nanoparticles with the size of 5~10 nm were dispersed uniformly on carbon powder surface. The specific capacitance of the composite increased with increasing quantity of iron oxide precipitate on the carbon powder up to a certain quantity. When the quantity of the iron oxide precipitate exceeds the threshold, however, the specific capacitance was rather reduced by the addition of precipitate. The iron oxide/carbon composite containing an optimum quantity (0.33 atomic %) of iron oxide precipitate exhibited the smallest resistance and the largest initial resistance slope.

Molybdenum Oxide Nanoparticles

In this study, molybdenum oxide/carbon nanocomposites (MOCNCs) were prepared by precipitating molybdenum oxide nanoparticles on activated carbon powder using liquid phase plasma process. The molybdenum oxide nanoparticles were impregnated on the AC surface and the amount impregnated was dependent on the concentration of the molybdenum precursor. MoO3 nanoparticles were predominantly precipitated and their size was about 20–80 nm. The specific capacitance of MOCNCs was increased with increasing the amount of molybdenum nanoparticles. Moreover, the resistances of MOCNCs were reduced than that of bare AC.
