Nano Cerium Dioxide Powder for Catalyst

Specification of CeO2 nanopowder:

Name: cerium dioxide/ceric oxide/ceria nanopowder

Particle size: 30-50nm

Purity: 99.9%

Appearance: light yellow solid powder

Nano CeO2 powder used as catalyst:

As a lanthanide element, cerium can lose two 6s electrons and one 5d electron to form a trivalent ion, and can also form a relatively stable 4f empty orbital due to the influence of the 4f electron arrangement, giving a tetravalent ion. This kind of valence characteristic makes it have good redox performance. Ceria not only has unique oxygen storage and release functions, but also is the oxide catalyst with the highest activity in the rare earth oxide series. Therefore, cerium dioxide can be used as a promoter to improve the catalytic performance of the catalyst in many occasions.

For example: Electrodes play a crucial role in the electrochemical reaction of fuel cells. Electrodes are not only an indispensable and important part of fuel cells, but also serve as catalysts for electrochemical reactions. The performance of transition metal oxide anodes is unmatched by many other materials. The main advantage lies in its multiple oxidation states. The coexistence of multiple valence states facilitates the free migration of electrons, so the activity of such electrocatalysts is higher than that of electrocatalysts with fixed valence states.

Ceric oxide(CeO2) nanoparticles are widely used as electrolyte materials, in solid oxide fuel cells, in solar cells, for automobile fuel oxidation, and as part of composite materials for oxidation of exhaust gas by tripartite catalysts.
