“…Effluents are filled with many types of ions and molecules which greatly modulate the rate of dye degradation (Senthilraja et al 2016). Ions such as Fe 2+ , Ca 2+ , Mg 2+ , Al 3+ , Na + , K + , NH 4 + , Cl − , PO 4 3− , SO 4 2− , HCO 3 − and NO 3 − are generally present in wastewater (Alahiane et al 2014;Azzaz et al 2018;Isari et al 2018).…”

Textile wastewaters contain refractory dyes that cause pollution and socioeconomic issues, thus calling for efficient remediation techniques such as photocatalysis. We review the fabrication, functionalization, performance and limitations of doped catalysts for degrading and mineralizing dyes. We present developments in photocatalyst immobilization and photocatalytic reactor design. Methods such as microwave irradiation, sonication and use of ionic liquids are emerging for the preparation of doped photocatalysts. Whilst single-dye systems have been extensively studied, there is limited knowledge on multipledye systems. Immobilization of photocatalysts is gaining popularity for large-scale application, but faces issues of erosion, corrosion, mechanical strength and structure integrity. Ecotoxicological studies are required in real environments to validate the potential applications of nanostructured doped photocatalysts.

“…Catalyst with 9% AC content (9 AC-ZnO) was found to be more efficient and its higher efficiency was due to the synergistic effect between ZnO and activated carbon. ZnO codoped by two transition metal ions like Cd-Ag-ZnO, Ce-Ag-ZnO, and Sn-Ag-ZnO are found to be more efficient in the photodegradation of dyes [46][47][48]. These bimetalic photocatalysts show higher photocatalytic activity for dye degrdation under UV (365 nm)/solar light than pure ZnO and commercial TiO 2 -P25.…”

Water pollution caused by hazardous substances has become a global concern. Textile and dyestuff industries produce large amounts of wastewater containing various dye pollutants. Most azo dyes are nonbiodegradable and their release into the environment poses a major threat to the surrounding ecosystems. Remediation of organic aquatic pollutants by photocatalytic oxidation has proven to be an attractive promising technology among the advanced oxidation processes. Semiconductor photocatalysis is a topic of current interest mainly in view of its potential application in the mineralization of pollutants.

“…Large quantities of nickel and sulfur in crude oil make the refining process heavier; unfortunately, the current conventional processes to remove these materials require a significant investment and long reaction times [188][189][190][191]. Wang et al Chitosan compounds have also been used as oxidants [193][194][195][196][197][198][199]. Heavily cross-linked chitosan possesses fewer active groups, and as a result, its chelating abilities, adsorption capacities, and sulfide oxidation abilities are decreased [192].…”
