Synthesis and characterization of Co3O4 spinel. – B. I. Ita
Co3O4 spinel has been obtained from cobalt (II) acetylacetonate by heating at 600oC in a blended solvent containing methanol and ethyleneglycol via a sol-gel technique. The Co3O4 has been found to possess a cubic structure having unit-cell parameters of a = b = c = 8.0773Ao. The mean-particle size of the Co3O4 is 32nm and the Braunner-Emmett-Teller (BET) surface area obtained by nitrogen adsorption was 80m2/g.
Keywords: Co3O4, particle size, cubic, sol-gel technique.
