Description générale

Cerium(IV) oxide (CeO₂) is a class of rare earth materials which can be synthesized by a variety of methods which include thermal hydrolysis and hydrothermal method. Its properties include a high refractive index, and dielectric constant.

Application

CeO₂ nanopowder can be used for a variety of applications such as biomedicine, semiconductors, and coating applications.

The additon of CeO₂ to CuO/TiO₂ increases specific surface area and inhibits sintering and pore size growth at high temperatures.

Advances in Materials for Solid Oxide Fuel Cells

As with all types of fuel cells, a Solid Oxide Fuel Cell (SOFC) is capable of efficiently transforming chemical energy into electrical energy.

Materials for Clean H² Production from Bioethanol Reforming

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.

Advanced Inorganic Materials for Solid State Lighting

White solid-state light can be generated using three different approaches: By employing three diodes that emit red, green and blue light respectively, by using a near-UV LED that excites several phosphors that emit over the complete spectral range, or the third, most widely used alternative entailing down-conversion of a portion of blue LED light to longer wavelengths in such a manner that white light emerges.
