Abstract

Zinc oxide (ZnO) is a versatile material having various applications in different disciplines. ZnO is an excellent alternative for TiO2 for the photodegradation of environmental pollutants. However, pure ZnO has some drawbacks, which limits photodegradation applications. ZnO photocatalytic activity is limited to the UV region. Moreover, ZnO gets agglomerated in aqueous media. To overcome such defects, some strategies have been suggested. For instance, simultaneous doping and usage of a suitable surface modifier changes the surface chemistry of ZnO. This chapter reviews the tailoring characteristics of ZnO through doping and surface modification. Synthesis is described with emphasis on the hydrothermal technique. The importance of organic pollutants such as azo dyes and industrial pollutants are discussed. We also review the characterization of nanomaterials, using for example powder X-ray diffraction, Fourier transmission infrared spectra, scanning electron microscopy, zeta potential, UV-Vis spectroscopy, and dynamic light scattering. Moreover, different intrinsic and extrinsic parameter affecting fabrication and application of nanomaterials are explained in detail.
