Synthesis and Characterization of Cerium-based Nanomaterials

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.&nbsp;<br>
