The thermodynamic redox properties of ceria and ceria zirconia solid solutions are analysed with a new methodology for modelling such systems based on the statistical mechanics of lattice configurations. A dilute species model of defect clusters , obeying the law of mass action, was sufficient to describe the system over the whole range of conditions, leading to a simple analytical equation of state for the system. This offers new physical insight into the redox properties of ceria based materials, and the theoretical methods developed should also be of great interest for other materials which exhibit continuous oxygen non-stoichiometry similar to ceria, such as perovskite oxides.

Functional oxide materials can show a plethora of emergent complex phenomena beyond their traditional role as dielectrics, including memristive effects, catalytic activity, energy conversion, and multiferroicity. Of further interest, nano-engineered oxides offer the possibility of realizing hitherto Of further interest, nano-engineered oxides offer the possibility of realizing hitherto unobserved phenomena due to their unique responsiveness to external stimuli, multiple order-parameter couplings, and increased volume-to-surface ratio. Consequently, oxide-based materials are becoming increasingly more important for a variety of applications including transparent electronics, optoelectronics, magnetoelectronics, photonics, spintronics, thermoelectrics, piezoelectrics, power harvesting, hydrogen production and storage, and catalysis for energy and environmental concerns. And yet, controlled synthesis and thorough microscopic understanding of these materials remain a challenge.

This chapter gives a general overview of synthesis and recent development of nickel oxide as a nonstoichiometric compound. We establish the synthesis chemistry of nickel oxide as a nonstoichiometric material, and hence successively introduce definitions and classifications of nonstoichiometric compounds as well as their point defects. The samples of nonstoichiometric nickel oxide are synthesized by thermal decomposition method. The nonstoichiometry of samples was then studied chemically by iodometric titration, and the results are further corroborated by excess oxygen obtained from the thermo-gravimetric analysis TGA. The change in oxidation state of nickel was studied by X-ray photoelectron spectroscopy XPS analysis.
