Abstract
This chapter pivots on the employment of Ce-based catalysts in numerous
catalytic applications glancing at the foremost commercial technologies due to their
high abundance in the earth’s crust. Ceria in essence to their proficiency to harmonize
Ce (III) & Ce (IV)-oxidation states depending on oxygen availability, which is known
as oxygen-storage capacity, is at the heart of the potentiality of Ce-based materials to
exemplify as a catalyst in numerous reactions. Ceria being one of the most auspicious
materials in use since 1980 onwards, has strongly dilated to affect several processes for
chemical transformations by and large for energy and environmental applications. In
this chapter, we will review some of the ingrained applications of Ce-based catalysts
and, we will try to display a brief rundown of emerging technologies in this ongoing
field to encourage further reading.
