Chemical Properties: 

Cobalt Oxide nanoparticle is a mixed valence compound of Co (II) and Co (III). It is soluble in nitric acid, and it easily absorbs moister but 
does not generate water compounds. It is broken into sub-cobalt oxides when heated above 1200 °C. 


Cobalt Oxide nanoparticles have applications in electronics, ceramics, and catalysis. It is used in lithium ion battery as electrode material, 
and in other electrochemical cells as electrode active material. It is used in semiconductors, temperature and gas sensors and in 
electronic ceramics. Cobalt Oxide nanoparticles are applied in solar energy as solar energy absorber. It is added to glass and porcelain as 
colorant and pigments. In catalysis, it is used as oxidant and catalyst for organic synthesis and catalyst carrier in chemical industry.
