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

  • Non-toxic
  • High photocatalytic activity
  • Good stability
Optically passive electrode for solid state electrochromic devices.
