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.
