Synthesis and Fabrication of Photoactive Nanocomposites Electrodes for the Degradation of Wastewater Pollutants

On the endeavor of wastewater treatment, synthesis and fabrication of various nanoparticle metal oxides is the pillar of continuation. As metal oxides possess different pros and cons, they are presently applied in their singular compounds and combined forms so as to pin point their definitive distinction on the efficiency and effectiveness occur on wastewater degradation. Hence, synthesis of metal oxides from nanoparticles and their fabrication to photoelectrode is paramount for clarification. Within this chapter, nanoparticles are explained; photoactive metal oxides are listed and discussed. Most centrally, the synthesis of photo-active semiconductors from nanoparticles and a fabrication of the photoactive metal oxides to semiconductor electrodes are detailed. Graphical Abstract: The purchased Nanoparticles are prepared as received through different steps. First, Nanoparticles are synthesized. Secondly, the intended Nanocomposites are formed using synthesis techniques such as sol-gel method. The formed Nanocomposite is characterized using different techniques. Thirdly, the Nanocomposite is pressed into a pellet. Fourthly, the copper wire is connected to the pellet using conductive silver paste. Finally, a transparent glass tube with opening at both ends sides was used.
