Synthesis of Zinc Oxide by Sol-Gel Method for Photoelectrochemical Cells

This book focuses on the study of synthesized ZnO powder using Zn(CH3COO)22H2O precursor, methanol (as solvent), and sodium hydroxide (NaOH) to vary the pH. The successfully synthesized ZnO powder from the sol-gel centrifugation and sol-gel storage methods were characterized and investigated by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, Fourier-transform infrared spectroscopy, UVvisible spectroscopy, and photoluminescence test to compare the properties of the nanoparticles. The best characteristic of the ZnO powder from both methods was observed when the powders were coated on an ITO glass to fabricate a PEC. The current densityvoltage performances of both PECs were investigated under luminescent and dark conditions.

Illustrates the complete process for the synthesis and characterization of ZnO nanocrystalline powder by solgel centrifugation and storage Demonstrates the application of ZnO nanocrystalline powder in photoelectrochemical cells
