“…Various nanomaterials have been used as catalysts due to their unique physiochemical properties, as this process is favorable thermodynamically but unfavorable kinetically in the absence of a catalyst. − These catalysts include silver nanoparticles (Ag-NPs), − silver-copper oxide nanocomposites, modified Ag-NPs, gold nanoparticles, − iron oxide nanoparticles, activated carbon, graphene oxide, , zinc oxide nanoparticles, zirconium oxide, Cu/sodium borosilicate nanocomposite, Pd/calcium lignosulfonate nanocomposite, lignin-derived (nano)materials, palladium nanoparticles, , and Cu NPs@Fe 3 O 4 . Nanomaterials can be generated through two primary approaches: the “top-down” and “bottom-up” methods.…”

Silver nanoparticles (Ag-NPs) exhibit vast potential in numerous applications, such as wastewater treatment and catalysis. In this study, we report the green synthesis of Ag-NPs using Acacia ehrenbergiana plant cortex extract to reduce cationic Rhodamine B (RhB) dye and for antibacterial and antifungal applications. The green synthesis of Ag-NPs involves three main phases: activation, growth, and termination. The shape and morphologies of the prepared Ag-NPs were studied through different analytical techniques. The results confirmed the successful preparation of Ag-NPs with a particle size distribution ranging from 1 to 40 nm. The Ag-NPs were used as a heterogeneous catalyst to reduce RhB dye from aqueous solutions in the presence of sodium borohydride (NaBH4). The results showed that 96% of catalytic reduction can be accomplished within 32 min using 20 μL of 0.05% Ag-NPs aqueous suspension in 100 μL of 1 mM RhB solution, 2 mL of deionized water, and 1 mL of 10 mM NaBH4 solution. The results followed a zero-order chemical kinetic (R 2 = 0.98) with reaction rate constant k as 0.059 mol L–1 s–1. Furthermore, the Ag-NPs were used as antibacterial and antifungal agents against 16 Gram-positive and Gram-negative bacteria as well as 1 fungus. The green synthesis of Ag-NPs is environmentally friendly and inexpensive, as well as yields highly stabilized nanoparticles by phytochemicals. The substantial results of catalytic reductions and antimicrobial activity reflect the novelty of the prepared Ag-NPs. These nanoparticles entrench the dye and effectively remove the microorganisms from polluted water.

“…Cell proliferation evaluation can also be conducted since SRB is bonded to cellular proteins quantitatively and hence can quantify the cells (2). Its carcinogenic behaviour and biorefractory aromatic pollutant nature, makes it a model dye for degradation studies (3,4,5). It does not degrade under normal conditions and remains in water as such.…”

Sulforhodamine B (C27H30N2O7S2) (SRB) is an amino-xanthene class, fluorescent dye, commonly used for in-vitro cytotoxicity monitoring and for the detection of drug-target interaction especially in the case of anti-cancer drugs. It does not degrade under normal conditions and remains in water as such. In accordance with the principles of green chemistry we have synthesized nano-structured Indium sulphide which demonstrates efficacy in photocatalytic degradation of this organic pollutant. The reusability of the photo catalyst was tested and it was found to degrade exponentially with recycling. The optimum SRB dye load on the photo catalyst was identified to be 0.28 M/gm for which a decay rate constant of ~ 4.58 x 10− 3 min− 1 was obtained. Beyond a critical SRB dye load, the photo catalysis involved direct rupture of the chromophore without an initial N-demethylation step.

“…Various techniques have been applied for the removal of inorganic metal ions from wastewaters, including ion exchange (Sharma et al 2021), adsorption (Huo et al 2019), and photocatalytic degradation (Jayakrishnan et al 2021), among which the adsorption method received broad attention due to its simplicity, high effectiveness, fast and safe, as well as the feasibility for the simultaneous removal of multiple pollutants (Abuzalat et al 2022). However, the adsorption method requires complex high-speed centrifugation or high-pressure ltration for the separation of the adsorbents after adsorption.…”

A novel adsorption composite composed of metal-organic frameworks with bifunctional groups of -NH2 and -COOH [UIO-66-NH2(-COOH)] loaded onto the fiberglass membrane labelled as F-MOFs-M was fabricated by a two-step method. This surface-modified composite could simultaneously capture both anionic and cationic heavy metal ions from wastewater, and the adsorption priority followed an order of SbO3−, CrO42−, AsO43−, Pb2+, and Ni2+. The adsorption capacity for AsO43−, CrO42−, SbO3−, Ni2+, and Pb2+ was 55 mg·g− 1, 189 mg·g− 1, 342 mg·g− 1, 16 mg·g− 1, and 133 mg·g− 1, respectively. It could be used for the quick removal of these toxic ions by withdrawing the membrane after adsorption. Additionally, the prepared F-MOFs-M provided an excellent stability in 7 days of continuous work, and could be easily regenerated and reused without significant decrease in removal performance even after 5 filtration cycles. The adsorption performances and their corresponding mechanisms were exploited by a series of advanced techniques. The MOF-derived materials loaded on membrane provide a new application scenario in the remediation of polluted water bodies.
