General description

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.

Currently, magnetic nanoparticles (MNPs) are attracting a lot of attention because of the possibility of many novel applications, especially in biomedical research.

Graphene is a unique two-dimensional (2D) structure of monolayer carbon atoms packed into a dense honeycomb crystal that has attracted great interest due to its diverse and fascinating properties.

Magnetic materials permeate numerous daily activities in our lives. They are essential components of a diversity of products including hard drives that reliably store information on our computers, decorative magnets that keep the shopping list attached to the refrigerator door, electric bicycles that speed our commute to work, as well as wind turbines for conversion of wind energy to electrical power.

The application of magnetism and magnetic materials pervades our modern civilization in the form of electrical power, communications and information storage.
