Development of high-performance bi-functional novel CdSnS₂ atom clusters for adsorption of rose Bengal and AOP-assisted degradation of methylene blue

Abstract

The fabrication of glycerol-mediated novel CdSnS2 atom clusters by one-pot co-precipitation is being undertaken to address rising concerns about environmental harm from hazardous organic compounds. The synthesized catalyst was assessed...

A pragmatic review on photocatalytic degradation of methyl orange dye pollutant using greenly biofunctionalized nanometallic materials: A focus on aquatic body

“…As a result of the aforesaid bottlenecks, the research community has affirmed that one of the best practical and economical solutions to remove MO is through the advanced oxidation process (AOP) photocatalytic degradation using NPs 19,38,39 . The AOP is a smooth technique that produces reactive oxygen species such as • OH and • O 2 − that initiate the oxidation reaction of pollutants 38–40 . This AOP technique offers the advantages of enhanced degradation efficiency, inexpensiveness, eco‐friendliness, and mild operating conditions alongside oxidative byproducts as a minor disadvantage 39,41,42 .…”

“…In this operation, a photocatalyst is stimulated with photon energy (≥ photocatalyst bandgap energy), resulting in the formation of photoinduced electron/hole (e − /h + ) pairs. The separation of photogenerated e − and h + is essential for the improved photocatalytic operation of the photocatalyst 38,39,43 . The charge transporters can be divided by adsorption on the surface of the photocatalyst or by the transfer of charges, which includes splitting e − and h + 39 .…”

One-pot synthesis of CdS/CeO2 heterojunction nanocomposite with tunable bandgap for the enhanced advanced oxidation process

“…Additionally, due to the high stability and non-biodegradability of dyes, they are often resistant to biological degradation 9 . Rose Bengal (RB) is a fluorescein dye, also known as Acid Red 94 used for a number of medical diagnostic procedures, such as liver function tests, staining of ocular necrotic tissue, and diagnosing conjunctivitis using devitalized corneal cells 10 . It damages mucous membranes when inhaled, making breathing uncomfortable for people.…”
