Description

Cerium(IV) oxide is widely applied as a solid electrolyte in fuel cells. It is also used in ceramics and to polish glass and stones. It can also be employed as a co-catalyst in many reactions. It is also used as an antioxidant and to generate hydrogen through water splitting. It is used as a high-temperature hydrocarbon oxidation catalyst in self-cleaning ovens. It can be used in infrared filters, incandescent mantles and sunscreens in combination with other materials. It finds use as a catalyst support and to sensitize photosensitive glass. It is utilized to increase specific surface area and inhibit sintering as well as pore size growth at a high temperature by addition with CuO/TiO₂.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
