“…The semiconductor materials that are applied in photoelectrocatalytic treatment of wastewater include photoanodes (n-type) and photocathodes (p-type) if oxidation or reduction is the main process at the interface [84]. Thus, photoelectrocatalysis is developed in such wastewater treatment field as: organic compounds oxidation [92,93]; inorganic ions reduction [94,95]; disinfection [96][97][98]; metal removal/recovery [99][100][101][102]; and, simultaneous generation of electricity and hydrogen [12,[103][104][105].…”

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.

“…PI-based composites have been extensively studied in the photocatalytic degradation of organic pollutants. Graphene-oxide-coated PI (GO/PI), nano-titanium dioxide/PI/nickel foam (TiO 2 /PI/Ni), silver phosphate/nitrogen-doped graphene/PI (Ag 3 PO 4 /NG/PI), phosphotungstate/PI (HPW/PI) ( Figure 22 ), black molybdenum oxide/PI (MoO 3 /PI), and zinc/PI (ZnS/PI) exhibit excellent degradation efficiency for 2,4-dichlorophenol [ 195 ], methylene blue [ 196 ], microcystin [ 197 ], imidacloprid [ 198 ], methyl orange [ 199 ], and tetracycline [ 200 ], respectively. The heterojunction or coordination bond formed between PI and other compounds will affect the photocatalytic activity of the composite material.…”

Polyimide (PI) is one of the most dominant engineering plastics with excellent thermal, mechanical, chemical stability and dielectric performance. Further improving the versatility of PIs is of great significance, broadening their application prospects. Thus, integrating functional nanofillers can finely tune the individual characteristic to a certain extent as required by the function. Integrating the two complementary benefits, PI-based composites strongly expand applications, such as aerospace, microelectronic devices, separation membranes, catalysis, and sensors. Here, from the perspective of system science, the recent studies of PI-based composites for molecular design, manufacturing process, combination methods, and the relevant applications are reviewed, more relevantly on the mechanism underlying the phenomena. Additionally, a systematic summary of the current challenges and further directions for PI nanocomposites is presented. Hence, the review will pave the way for future studies.

“…Lei et al developed a TiO 2 /PI/Ni foam photoanode for MB degradation by dispersing a porous nanostructured TiO 2 film in a PI/Ni foam substrate. 93 Although Ni foam possesses many advantages owing to its large surface area, evenly distributed pore size and high conductivity, it is rarely used as a conductive support due to its facile oxidation during the photoelectrochemical reaction. To suppress this, a protective layer was produced on the surface by filling the Ni foam with a polymer.…”
