Green Synthesis of Silver Nanoparticles Using Acacia ehrenbergiana Plant Cortex Extract for Efficient Removal of Rhodamine B Cationic Dye from Wastewater and the Evaluation of Antimicrobial Activity

ACS Omega, Journal Year: 2023, Volume and Issue: 8(21), P. 18901 - 18914

Published: May 15, 2023

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 for antibacterial antifungal applications. The involves three main phases: activation, growth, termination. shape morphologies prepared were studied through different analytical techniques. results confirmed successful preparation with a particle size distribution ranging from 1 40 nm. used heterogeneous catalyst RhB aqueous solutions presence sodium borohydride (NaBH4). showed that 96% catalytic reduction can be accomplished within 32 min 20 μL 0.05% suspension 100 mM solution, 2 mL deionized water, 10 NaBH4 solution. followed zero-order chemical kinetic (R2 = 0.98) reaction rate constant k 0.059 mol L-1 s-1. Furthermore, agents against 16 Gram-positive Gram-negative bacteria well fungus. is environmentally friendly inexpensive, yields highly stabilized by phytochemicals. substantial reductions antimicrobial activity reflect novelty Ag-NPs.

Fabrication of Effective Co-SnO2/SGCN Photocatalysts for the Removal of Organic Pollutants and Pathogen Inactivation

Crystals, Journal Year: 2023, Volume and Issue: 13(2), P. 163 - 163

Published: Jan. 17, 2023

Substantial improvement is needed in efficient and affordable decolorization disinfection methods to solve the issues caused by dyes harmful bacteria water wastewater. This work involves photocatalytic degradation of methylene blue (MB) as well gram-negative gram-positive cobalt-doped tin oxide (Co-SnO2) nanoparticles (NPs) Co-SnO2/SGCN (sulfur-doped graphitic carbon nitride) nanocomposites (NCs) under sunlight. The coprecipitation approach was used synthesize photocatalysts. Maximum seen with 7% Co-SnO2 NPs compared other (1, 3, 5, 9 wt.%) NPs. were then homogenized different amounts (10, 30, 50, 70 weight %) sulfur-doped nitride (SGCN) develop heterostructures most significant degree MB degradation. synthesized samples identified modern characterization such FT-IR, SEM, EDX, UV-visible, XRD spectroscopies. Co-SnO2/50% SGCN composites showed a increase degraded 96% after 150 min sunlight irradiation. Both (E. coli) (B. subtiles) bacterial strains subjected antibacterial activity. All shown have vigorous activity against bacteria, but exhibited maximum bactericidal action. Thus, proposed NC an organic/inorganic photocatalyst that recyclable stable without lowering efficiency. Hence, SGCNNC has potential be employed treatment dual-functional material simultaneously removes organic pollutants eradicates bacteria.

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

Applied Organometallic Chemistry, Journal Year: 2023, Volume and Issue: 37(7)

Published: April 20, 2023

Water is the source of life. But unfortunately, 80% wastewater discharged into aquatic body untreated globally, which industry responsible for 70% such water abstraction through discharge pollutants like methyl orange. According to WWAP, pollution kills 100 million individuals, 2 marine animals, and seabirds yearly, by 2025, it forecasted that ~1000 inhabitants in arid zones will experience severe crisis, thus, security has become focal outcry due daily environmental escalation caused rapid growth industries population. Recently, biosynthesized nanoparticles as photocatalysts have answered call sustainable treatment orange dye effluent photodegradation because their efficient photoactivity, inexpensiveness, eco‐benignness. In this review, photocatalytic‐degradation mechanism pathways environment presence • OH − O using green were mechanistically discussed. The highest degradation efficiency was found be 100%, final mineralization products H CO , least time taken min with silver being most commonly used degrader plant extracts employed bioreductant biosynthesis nanoparticles.

Abstract The current study reported a facile co-precipitation technique for synthesizing novel NiCo 2 S 4 /chitosan nanocomposite. photocatalytic activity of the prepared nanocomposite was evaluated using congo red (CR) dye as target pollutant. central composite design employed to examine impact different reaction conditions on CR degradation. This selected pH, photocatalyst loading, initial concentration and time parameters, while degradation efficiency (%) response. A desirability factor 1 suggested adequacy model. Maximum 93.46% 35 ppm solution observed after 60 min visible light irradiation. response surface methodology (RSM) is helpful predict optimum photodegradation dye. Moreover, /Ch displayed high recyclability reusability up four consecutive cycles. present suggests that could prove be viable treatment dye-contaminated wastewater.
