“…The heterostructures, which are multi-component photocatalysts, benefit from a broad light spectrum, allowing them to use UV, visible, or near-infrared photoexcitation depending on their energy band gaps and capacity to produce oxidative radicals for organic pollutants removal. Several processes may be used to create the heterostructure: type I junctions (Baneto et al 2015 ), type II junctions (Teixeira et al 2019 ), Schottky junctions (Wang et al 2019 ), Z-scheme mechanisms (Abdullah et al 2019 ), or S-scheme mechanisms (Albornoz et al 2021 ). Except for the Schottky junction, which may have one semiconductor connected with metal, these heterostructures contain at least two semiconductors with the appropriate location of energy bands.…”

Wastewaters often contain toxic organic pollutants with a possible adverse effect on human health and aquatic life upon exposure. Persistent organic pollutants such as dyes and pesticides, pharmaceuticals, and other chemicals are gaining extensive attention. Water treatment utilizing photocatalysis has recently received a lot of interest. Photocatalysis is cutting-edge, alternative technology. It has various advantages, including functioning at normal temperatures and atmospheric pressure, cheap prices, no secondary waste creation, and being readily available and easily accessible. This review presented a comprehensive overview of the advances in the application of the photocatalytic process in the treatment of highly polluted industrial wastewater. The analysis of various literature revealed that TiO 2 -based photocatalysts are highly effective in degrading organic pollutants from wastewater compared to other forms of wastewater treatment technologies. The electrical structure of a semiconductor plays a vital role in the photocatalyst's mechanism. The morphology of a photocatalyst is determined by the synthesis method, chemical content, and technical characteristics. The scaled-up of the photoreactors will significantly help in curbing the effect of organic pollutants in wastewater.

“…The multi-component photocatalyst, called heterostructures, benefit from the extended light spectra being able to use UV, visible or near infra-red photoexcitation depending on their energy band gaps values and ability to produce oxidative radicals involved in organic pollutants removal. The heterostructure can follow several mechanisms: type I junctions [47], type II junctions [48], Schottky junctions [49], Z-scheme mechanism [50] or S-scheme mechanisms [51]. These heterostructures contain at least two semiconductors with suitable position of energy bands, excepting Schottky junction, which may include one semiconductor coupled with a metal.…”

The organic pollutants removal by conventional methods (adsorption, coagulation, filtration, microorganism and enzymes) showed important limitation due to the reluctance of these molecules. An alternative to this issue is represented by the photocatalytic technology considered as an advanced oxidation process (AOP). The photoreactors design and concepts vary based on the working regime (static or dynamic), photocatalyst morphology (powders or bulk) and volume. This mini-review aims to provide specific guidelines on the correlations between the photoreactor concept characteristics (working regime, volume and flow rate), irradiation scenarios (light spectra, irradiation period and intensity) and the photocatalytic process parameters (photocatalyst materials and dosage, pollutant type and concentration, pollutant removal efficiency and constant rate). The paper considers two main photoreactor geometries (cylindrical and rectangular) and analyses the influence of parameters optimization on the overall photocatalytic efficiency. Based on the systematic evaluation of the input data reported in the scientific papers, several perspectives regarding the photocatalytic reactors' optimization were included.

“…This recombination can be reduced by doping TiO 2 with semiconductors such as RuO 2 , WO 3 , CeO 2 . However, these materials are considered critical raw materials due to their high worldwide demand coupled with low availability, which requires the development of materials without using critical raw materials developed and used in the doping of TiO 2 catalyst ( Albornoz et al, 2020 ).…”
