Properties and Synthesis of Metal Oxide Nanoparticles in Electrochemistry

The synthesis and study of “metal oxide nanoparticles”, has gain greater attention over the past 10 years among interdisciplinary researchers. The major interest may be as a result of their unique physical and chemical properties, which gives rise to their various industrial usage in the field of catalysis, electronics, solar energy conversion, and others. As the particle size diminishes, the ratio of surface atoms to those inherent rises, enabling the surface properties to dictate the overall properties of the nano-materials. Also, metal oxide nanoparticles manifest different optical and electrical properties in proportion to that of the bulk material. Hence, as the size of the solid becomes smaller, the band gap becomes larger. This, therefore, gave scientists the unique opportunity of nanofabrication synthesizing highly complex nanostructure with different electronic and optical properties just by manipulating its particle size.
