General description

CeO2-ZrO2 composites have a good crystal structure, higher specific surface area, lower band-gap energy, and smaller grain size. It forms p-n heterojunction and is widely used in the field of photocatalysis and oxygen storage.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and is intended for Molecular Solar Thermal Energy Storage Systems (MOST). Click here for more information.

Application

CeO2-ZrO2 can be used as a catalyst for water-splitting reactions and photocatalytic degradation of organic pollutants.

Pt/CeO2–ZrO2 can be used as a catalyst in the dry reformation of methane.

It can also be used to prepare optically passive electrodes for solid-state electrochromic devices.

Features and Benefits
