N2 - Superfine cobaltous oxide nanoparticles (CoONPs) of ~2.5nm diameter were synthesized at high rate via discharge plasma operated in an aqueous solution of Co(II) acetate. Two potential routes are proposed for the CoONP formation: one is the plasma-induced electrolysis of the aqueous solution of Co(II) acetate, and the other is the oxidization of neutral Co, which is formed by the plasma-induced reduction of Co(II). In addition, the resultant CoONPs are soluble in ethanol but insoluble in water, which is attributed to the surface conjugation of functional groups of CH 3- produced by the plasma-induced electrolysis of an aqueous solution of Co(II) acetate.
