Preparation of Co3O4 Nanoparticles by Polymer Combustion Methods
Abstract:
Co3O4 nanoparticles were prepared by mixing polyvinylalcohol(PVA)and Co(NO3)2 in a mole ratio of 1:3~4,at 100~130℃ to evaporate and remove water,and calcining at 400℃ for 2 h.The structure,crystal type and surface appearance were characterized by IR,XRD and TEM.The results showed that metal carbonate was formed using the polymer combustion methods,and the Co3O4 gave a cubic polygon appearance.Agglomerate free,well dispersive Co3O4 nanoparticles with the cubic structure and the average size of ca.33 nm could be obtained from carbonated precursor by this simple and economical methods
