Cobalt Oxide Nanoparticles (Co₃O₄)
Our cobalt oxide nanoparticles are synthesised by sol-gel process in oxygen-rich ethanolic environment. The sub-5nm cobalt oxide particles exhibit excellent dispersibility in polar solvents. The absence of bulky ligands during the synthesis makes the particles’ surface accessible to chemicals, an important feature in heterogeneous catalysis.
Co3O4 nanoparticles are used in a variety of applications including photocatalysis, energy storage, gas sensing and optics.
We offer Co3O4 particles in different sizes, both in solution and in powder form.
