Description générale

Cobalt oxide is a p-type semiconductor thatbelongs to the normal spinel crystal structure with cubic close packing ofoxide ions. It has variable oxidation states and multiple band gapenergies (2.28eV and 1.57eV). It is paramagnetic at room temperature.

Application

Cobalt(II,III) oxide nanoparticles can be used:

  • To modify the glassycarbon electrode for the detection of As(III) at nanomolar concentrationrange.
  • To prepare a robust photocatalyst along withcarbon nanospheres for dye degradation and hydrogen evolution reaction.
  • As an electrodematerial in the preparation of supercapacitors.
