ZnO Nanocrystalline Metal Oxide Semiconductor Via Sol Gel Method

This chapter discussed the fundamentals, properties and applications. The ZnO properties will mainly focus on structural, electronic and optical. Finally, this chapter discussed the synthesis sol–gel method.

ZnO: Photoelectrochemical Cells Analysis

The photoelectrochemical cells (PEC) basic concept and its construction is presented in this chapter. Two types of PEC are chosen as it were fabricated based on the optimal properties of ZnO synthesized by sol–gel process. Both of PEC performances are explained by the current density–voltage (J–V) properties of the PEC under illuminated and dark conditions.

ZnO: Effect of pH on the Sol–Gel Process

The technique of synthesis ZnO via sol–gel process at various pH values is presented in this chapter. The characterization methodologies such as X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), crystallite and average particle size analysis, Fourier transform infrared spectroscopy (FTIR), mechanism of growth analysis, and photoluminescence (PL) analysis of ZnO are explained in details.

ZnO: Effect of Centrifugation and Storage on Sol–Gel Process

The properties of ZnO synthesized by sol–gel centrifugation (SGC) and sol–gel storage (SGS) are presented in this chapter. Furthermore, the physical appearance of ZnO has been discussed. The ZnO structural, morphological and optical properties are characterize using X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and UV-visible (UV-vis) spectroscopy.
