Nanocrystalline functional oxide materials

Abstract

Nanoparticles are small clusters of atoms about 1-100 nm long. The term “nano” derives from the Greek word nanos, which means dwarf or extremely small. A nanometer is a billionth of a meter or 10-9 m. Nanostructured materials have attracted the attention of different types of people such as scientists, engineers, etc. Essentially, the reason is that nanocrystals nanocrystal in the 1-10 nm range make up a new realm of matter in which physical and chemical properties change as size changes. Metal oxide nanoparticles metal oxide nanoparticle are an important class of materials for their optical, magnetic, and electronic properties and have a wide range of applications such as in catalysts, sensors, optical materials, electrical materials, and magnetic storage. Synthesis routes synthesis route for nanoparticles can be broadly classified into solid-state and soft chemical routes such as gel combustion, coprecipitation, sol-gel, hydrothermal/solvothermal, sonochemical, template synthesis, etc. This chapter deals with the various properties of nanoparticles synthesized using different techniques. The application of nanooxides nanooxide as sorbents for environmental remediation is also discussed in this chapter.
