“…Titanium dioxide is the most common semiconductor material that is applied in photoelectrocatalytic treatment of wastewater as electrode material, due to its low cost, nontoxicity, and resistance to photocorrosion [107]. TiO 2 occurs in three polymorphs-the stable rutile, metastable anatase, and brookite, showing different properties and band gaps, i.e.…”

“…The other semiconductors that are presented in Table 3 reveal lower band gaps and they can be excited by visible irradiation. Especially, WO 3 draws attention due to its high stability in acidic solutions, resistance to photocorrosion, high conductivity, and the possibility of photoexcitation by VIS irradiation or sunlight [107,145]. Thus, this semiconductor seems to be most commonly applied in photodegradation of pollutants present in wastewater, except for TiO 2 (Table 4).…”

“…This is related to different Fermi levels in the semiconductor and noble metal dopant, being characterized by the work function of the dopant and band structure of the semiconductor. Doping results in the formation of Schottky barrier in the doped material [84,107]. Subsequently, the noble metal acts as an electron trap and promotes the interfacial electron transfer from CB of the semiconductor into the metal nanoparticles and recombination of photogenerated e − /h + pairs is reduced.…”

Industrial sources of environmental pollution generate huge amounts of industrial wastewater containing various recalcitrant organic and inorganic pollutants that are hazardous to the environment. On the other hand, industrial wastewater can be regarded as a prospective source of fresh water, energy, and valuable raw materials. Conventional sewage treatment systems are often not efficient enough for the complete degradation of pollutants and they are characterized by high energy consumption. Moreover, the chemical energy that is stored in the wastewater is wasted. A solution to these problems is an application of photoelectrocatalytic treatment methods, especially when they are coupled with energy generation. The paper presents a general overview of the semiconductor materials applied as photoelectrodes in the treatment of various pollutants. The fundamentals of photoelectrocatalytic reactions and the mechanism of pollutants treatment as well as parameters affecting the treatment process are presented. Examples of different semiconductor photoelectrodes that are applied in treatment processes are described in order to present the strengths and weaknesses of the photoelectrocatalytic treatment of industrial wastewater. This overview is an addition to the existing knowledge with a particular focus on the main experimental conditions employed in the photoelectrocatalytic degradation of various pollutants with the application of semiconductor photoelectrodes.

Gupta for allowing the use of his dynamic light scattering equipment, and Dr. Norma Alcantar and her graduate student, Eva Williams, for teaching me to make lipid vesicles in their lab. A special "thank you" to Mr. Charles Garretson, our exceptional lab manager and a truly brilliant engineer who can build almost anything that can be conceived. I also want to thank Mr. Ed Haller for his patience in teaching me to use the transmission electron microscope. I am indebted to my colleagues, who offered their assistance when I needed it the most;
