When water vapor was used, the catalyst would strip out its oxygen to reform ceriumdioxide.
如果用于分解的物质是水蒸汽，那么二氧化铈催化剂还可以将分解出的氧气用于二氧化铈的再生。

Ceriumdioxide has high refractive index and dielectric constant and ultraviolet absorption which may be useful for various optical and electronic applications.
二氧化铈具有高折射率、介电常数和紫外吸收率，因此它广泛地应用于各种光学和电子器件。
