Bimetallic Co-Fe-BTC/CN nanocomposite synthesised via a microwave-assisted hydrothermal method for highly efficient Reactive Yellow 145 dye photodegradation

Exploring the potential of ZnO–Ag@AgBr/SBA-15 Z-scheme heterostructure for efficient wastewater treatment: synthesis, characterization, and real-world applications

“…5–7 Among these methods, photocatalysis has the potential to partially or completely mineralize harmful pollutants like dyes and phenolic compounds into less toxic or benign substances like CO 2 and H 2 O. 8,9…”

Enhanced photocatalytic degradation of direct blue 71 dye using TiO2-PAA-GO composite in aqueous solution

“…Environmental pollution of soil, water, and air is a growing concern. One of the causes of water pollution is the discharge and disposal of industrial wastewater containing dyes [1][2][3]. Dyes are present from various industries, including printing, electroplating, and textiles [4,5].…”

“…Dyes are present from various industries, including printing, electroplating, and textiles [4,5]. Many types of dyes, such as acid black 210, methylene blue (MB), acid black 234, mordant black 1, reactive yellow 145 (RY-145), and Direct Blue 71(DB-71), are toxic, mutagenic, and carcinogenic [1,2]. In particular, DB-71 is very commonly used in textile, plastic, and footwear industries to color products such as paper, plastic, cellulose fiber, and viscose fiber [6].…”

“…To prevent health and environmental hazards, appropriate actions should be taken to remove dyes before discharging effluents containing them [8]. Several methods have been used to remove dyes from industrial wastewater, including coagulation and flocculation, biological treatment, chemical oxidation, photocatalysis, and electrochemical treatment [2]. Photocatalysis, in particular, has many outstanding advantages over other methods, such as fast decomposition rate, high selectivity of CO 2 and H 2 O, high durability, room temperature operation, sustainability, and cost savings [1][2][3].…”

Various substances, such as titanium dioxide (TiO 2 ), zinc oxide (ZnO), silver bromide (AgBr), cadmium sulfide (CdS), and graphitic carbon nitride (g-C 3 N 4 ) have been used as promising photocatalysts in environmental waste treatment systems [9][10][11][12].…”
