ABSTRACT
The use of metal oxide nanoparticles has great potential in many applications, such as technical, medicine, and energy. The adept preparation and synthesis of nanomaterials/hybrid nanocomposites made up of noble metals, such as Ag, Pt, Au, and Pd, and some important metal oxides, such as TiO2, Cu2O, ZnO, MnO2, and CeO2, have received more attention for applications in energy storage devices, photocatalysis reactions, drug delivery systems, solar cells, and many other significant areas. Nanostructured metal oxides are generally being used as novel catalysts in many process industries for enhancing the functional and structural properties of the material. In this chapter, we mainly focus on the synthesis and various applications of nanostructured metal oxides in a different field. This chapter provides a detailed viewpoint on the nanostructured metal oxides that are used for various applications. The discussion in this chapter highlights different preparation methods of nanostructured metal oxide materials and their mechanistic features in the energy sector and wastewater treatment. Finally, we conclude with the future scope and prospects of various nanostructured metal oxides.
