Preparation of nanocrystalline CeO2 by the precipitation method and its improved methane oxidation activity
Nanocrystalline CeO2 as small as 5 nm was successfully prepared by the precipitation method using hydrogen peroxide as an oxidizer. The methane oxidation temperature of this nanocrystalline CeO2 dropped about 100 degrees C as compared with microcrystalline CeO2.
