General description

Cobalt(II,III) oxide, also knownas tricobalt tetraoxide is a black antiferrimagnetic solid. Our Co3O4 is a powder with a particle size of <10 μm and a cobalt concentration between 71-74%. A high melting point of 895 °C (dec.) indicates that Co3O4 can with stand elevated temperatures without decomposing, making it suitable for high-temperature applications such as heterogeneous catalysis in industrial processes. Co3O4 is also widely used in the battery industry as a precursor to fabricate cathode materials, such as lithium cobalt oxide and lithium nickel manganese cobalt oxide, for Li-ion batteries.

Application


  • Synthesis of diphenylalanine/cobalt oxide hybrid nanowires and their application to energy storage.: This study demonstrates the synthesis of hybrid nanowires using diphenylalanine and cobalt oxide, highlighting their potential for enhancing energy storage capacities (Ryu et al., 2010).
