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.

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

Advances in Materials for Solid Oxide Fuel Cells

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
