Abstract
The redox behavior of cerium is responsible for its high technological
importance since ceria serves as a potential material in assorted applications. Changes
in the optical, electrical, magnetic, and catalytic behavior of ceria can be brought about
by employing different methodologies and reaction conditions. The high thermal and
structural stability of ceria offers its utilization as a host lattice for various doping
schemes. The incorporation of dopant elements beautifies the lattice by generating
oxygen vacancies and thereby creating various interesting properties. Aiming with the
stabilization of ceria and ceria-based compounds in nano-dimensions also opens up
various new possibilities to explore it further for numerous useful applications.

Abstract
Pristine ceria is an extensively explored nanomaterial. In order to improve
physiochemical properties of ceria and ceria based materials, a different synthetic
strategy has been employed which has been highlighted in the current chapter. The
high stability of pristine ceria offers an opportunity to utilize it as a host lattice against
the doping/substitution of alkali metals, alkaline earth metals, transition metals, rare
earth and noble metals. This way incorporation of different valence metals ion into
ceria causes structural distortion which further facilitates alteration of the physical and
chemical properties of host lattice. Diverse synthetic conditions are used to stabilize
ceria and ceria-based materials in nano-resime having morphologies such as nanowires,
nanocubes, nanospheres, nanotubes and many more. Thus, different morphologies of
ceria and ceria-based materials are mainly applicable for their high technological
importance. The synthesized samples can be characterized by using powder X-ray
diffraction, Raman scanning electron microscopy, energy dispersive spectroscopy,
transmission electron microscopy and X-ray photoelectron spectroscopy.

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.

Abstract
This chapter pivots on Ce-based catalysts’ employment in numerous
catalytic applications glancing at the foremost commercial technologies due to their
high abundance in the earth's crust. Ceria - CeO2
is considered the most stable oxide
which confirms that Ce3+ prefers the oxidation state than the Ce4+ oxidation state. This
is also known as oxygen - storage capacity. CeO2
shows good photocatalytic activity.
This chapter explores the important properties of Ce and CeO2
with a comparison of
their bulk properties with their properties at the nanoscale. Further, different synthesis
processes of Ce and CeO2
nanoparticles have been discussed. Later, the chapter
addresses the mechanism of photocatalysis using CeO2
nanoparticles. Further, the
chapter discusses applications and studies of doped CeO2
based photocatalysts, and we
will try to display a brief rundown of emerging technologies in the ongoing field to
encourage further reading.

Abstract
Cerium-based materials have established themselves as biologically active
materials with a wide range of pharmacological benefits. In particular, Nanoceria has
been proven to be the most versatile and effective therapeutic agent due to its surface
area-to-volume ratio. In this chapter, we made an attempt to discuss all important
therapeutic applications of Cerium based materials. Also, the mechanistic course of
action of cerium-based materials has been emphasized in this chapter. Moreover, the
possible toxicity of cerium-based materials in the biological system has been reviewed
in the later section of this chapter.
Introduction
Cerium is the most abundant metal of rare-earth elements. It can be used to make materials such as phosphors and alloys, that have applications in various applied fields (like electronics, magnetics and heterogeneous catalysis) and devices (like catalytic converters and gas mantles). Cerium-Based Materials: Synthesis, Properties and Applications presents detailed knowledge about cerium materials. Starting with the history of cerium-based materials, it gives an introduction to the synthesis of chemicals like cerium oxides and composites. This is followed by information about characterization of cerium nanoparticles and industrial applications of cerium-based materials, with a focus on catalysis, biomedical engineering and pharmaceutical chemistry. This book is an essential reference for researchers and chemical engineers who want a summary of cerium materials and its applications.
