In the last 3 years alone, over 10,000 publications have appeared on the topic of dye removal, including over 300 reviews. Thus, the topic is very relevant, although there are few articles on the practical applications on an industrial scale of the results obtained in research laboratories. Therefore, in this review, we focus on advanced oxidation methods integrated with biological methods, widely recognized as highly efficient treatments for recalcitrant wastewater, that have the best chance of industrial application. It is extremely important to know all the phenomena and mechanisms that occur during the process of removing dyestuffs and the products of their degradation from wastewater to prevent their penetration into drinking water sources. Therefore, particular attention is paid to understanding the mechanisms of both chemical and biological degradation of dyes, and the kinetics of these processes, which are important from a design point of view, as well as the performance and implementation of these operations on a larger scale.

“…In addition, the nature and stability, recyclability of the catalyst, the presence of scavenging inorganic ions and the influence of natural organic matter on the ozonation should also be accounted for (Nawrocki and Kasprzyk-Hordern 2010). Furthermore, the heterogeneous catalyst can enable the adsorption of both the O3 and pollutant on the catalyst surface to facilitate their surface reaction (Bilińska et al 2020). It is essential with catalysts to investigate any potential leaching of metal ions which will influence the efficiency, mechanism and recyclability as well as potentially creating polluting ions (De Luca et al 2014).…”

Advanced oxidation processes (AOPs) are chemical treatment techniques used in water and wastewater treatment. To enhance the water treatment efficiency, ultraviolet (UV), visible (Vis) or solar light irradiation and ultrasound technology (US) are frequently used. UV and Vis irradiation include bands from 100 to 400 nm and from 400 to 800 nm, respectively. Solar light at the Earth surface has a wavelength between 300 nm to 1 mm, including UV, Vis and Infrared (IR) light regions. US is a high-frequency sound, which can decompose many organic pollutants. To accelerate the AOPs, catalysts are widely used. These compounds increase the rate of the reaction without being used up. Introduction: Water TreatmentConventional water treatment and sustainability UN Sustainable development goal 6: Clean water and sanitation requires greatly improved treatment for the estimated 80% of wastewater that is released untreated, where this climbs to 95% in some developing countries (WWAP 2017). Such wastewater varies in both its source, such as from industry, urban and agriculture, and components, which may vary over time and location. There are also various emerging pollutants in water, such as antibiotics, pesticides and microplastics (Zhang et al. 2020). A key aspect to meet the sustainable development goal is for wastewater to be viewed more as a resource than as a burden to facilitate its role within a circular economy. Such an approach may become more economically sustainable if resources can also be recovered from wastewater, for instance, the recovery of valuable nutrients (Collinson and García 2013). Wastewater treatment will also become more sustainable through the use of less environmentally harmful chemicals or processes, for instance applying catalysts to reduce the use of chemicals and energy, while also finding synergies with other technologies such as renewable energy (Anastas and Zimmerman 2018; Prasannamedha and Kumar 2020). Current challengesChlorine is widely used for the disinfection of drinking water and the residual chlorine in water is important to avoid recontamination during transport and storage. The continued development of water treatment is important to avoid the possible disinfection by-products arising from disinfection using chlorine (Miklos et al. 2018). Furthermore, the efficient removal of heavy metals, persistent organic pollutants (POPs) and emerging pollutants from water provides a range of current challenges in water treatment. For instance, POPs include antibiotics, dyes and polyaromatic hydrocarbons (PAHs) which arise from a variety of sources and may not be effectively removed from water using chlorine so either an advanced oxidation process (AOP) is required or adsorption as will be discussed below. Similarly, the development of more sustainable flocculants for water treatment is also an active area

“…[ 23 , 24 ] The alkaline medium is also required in water treatment, papermaking, textile industry, and many other important fields related to H 2 O 2 . [ 25 ] In addition, the alkaline condition is less corrosive and enables the long‐term activity of TMCs. [ 26 ] Therefore, rational design of TMCs as effective 2e‐ORR electrocatalysts in alkaline condition is highly attractive, yet fairly challenging.…”

High‐performance transition metal chalcogenides (TMCs) as electrocatalysts for two‐electron oxygen reduction reaction (2e‐ORR) in alkaline medium are promising for hydrogen peroxide (H 2 O 2 ) production, but their synthesis remains challenging. In this work, a titanium‐doped zinc–cobalt sulfide hollow superstructure (Ti–ZnCoS HSS) is rationally designed as an efficient electrocatalyst for H 2 O 2 electrosynthesis. Synthesized by using hybrid metal–organic frameworks (MOFs) as precursors after sulfidation treatment, the resultant Ti–ZnCoS HSS exhibits a hollow‐on‐hollow superstructure with small nanocages assembled around a large cake‐like cavity. Both experimental and simulation results demonstrate that the polymetallic composition tailors the d‐band center and binding energy with oxygen species. Moreover, the hollow superstructure provides abundant active sites and promotes mass and electron transfer. The synergistic d‐band center and superstructure engineering at both atomic and nanoscale levels lead to the remarkable 2e‐ORR performance of Ti–ZnCoS HSS with a high selectivity of 98%, activity (potential at 1 mA cm −2 of 0.774 V vs reversible hydrogen electrode (RHE)), a H 2 O 2 production rate of 675 mmol h –1 g cat –1 , and long‐term stability in alkaline condition, among the best 2e‐ORR electrocatalysts reported to date. This strategy paves the way toward the rational design of polymetallic TMCs as advanced 2e‐ORR catalysts.
