Abstract: Mixed Co3O4 - CuO - ZrO2 nanoparticles were synthesized via wet chemical method. Optical, structural, morphological and thermal properties of mixed Co3O4 - CuO - ZrO2 nanoparticles were studied using UV- DRS, SEM, TEM, TG/DTG and DSC. UV-Vis diffuse reflectance spectrum indicated that the band gap of Co3O4 - CuO - ZrO2 nanoparticles is about 2.37 - 2.52 eV. The synthesized Co3O4 - CuO - ZrO2 nanoparticles have irregular morphology with size ranging from 10 - 40nm as evident from SEM and TEM micrographs. TG/DTG and DSC studies revealed good thermal stability of the Co3O4 - CuO - ZrO2 nanoparticles. From the TG analysis, a total mass loss of only 28.86% was observed in the temperature range from RT to 1200Â°C
