Used as a precursor in the synthesis of cobalt-based catalysts for industrial oxidation reactions. Employed in electrochemical applications, including battery materials and supercapacitors, due to its redox activity. Serves as a pigment in ceramics and glass, providing a stable blue color. Applied in the preparation of cobalt phosphate coatings for corrosion protection. Also investigated for use in water oxidation catalysts for renewable energy systems and magnetic materials due to its interesting electrical and magnetic properties.
