“…According to Shan et al (2020) , there was very little activity loss, and the Ag/TiO 2 /biochar composite catalysts showed good stability for up to five cycles. As stated by Paramesh et al (2021) , the recovered catalyst exhibited comparable activity for up to five cycles, and the Ag-NPs were recovered in good yield. The progressive degradation of catalyst performance was primarily caused by metal leaching concentration, adsorption of intermediate products on catalytic sites, and degradation of catalytic sites ( Chen et al, 2022 ).…”

In the current study, endophytic Aspergillus hiratsukae was used for the biosynthesis of silver nanoparticles (Ag-NPs) for the first time. The characterizations were performed using X ray diffraction (XRD), Transmission electron microscopy (TEM), Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM–EDX), Dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FT-IR), and UV–Vis spectroscopy. The obtained results demonstrated the successful formation of crystalline, spherical Ag-NPs with particle diameters ranging from 16 to 31 nm. The FT-IR studied and displayed the various functional groups involved, which played a role in capping and reducing agents for Ag-NPs production. The SEM–EDX revealed that the main constituent of the AS-formed sample was primarily Ag, with a weight percentage of 64.2%. The mycosynthesized Ag-NPs were assessed for antimicrobial as well as photocatalytic activities. The antimicrobial results indicated that the synthesized Ag-NPs possess notable antibacterial efficacy against Staphylococcus aureus, Bacillus subtilis, and Escherichia coli, with minimum inhibitory concentrations (MICs) of Ag-NPs ranging from 62.5 to 250 μg/mL. Moreover, the biosynthesized Ag-NPs demonstrated weak antifungal activity against Aspergillus brasiliensis and Candida albicans, with MICs of 500 and 1,000 μg/mL, respectively. In addition, the mycosynthesized Ag-NPs exhibited photocatalytic activity toward acid black 2 (nigrosine) dye under both light and dark stimulation. Notably, After 300 min exposure to light, the nigrosine dye was degraded by 93%. In contrast, 51% degradation was observed after 300 min in darkness. In conclusion, Ag-NPs were successfully biosynthesized using endophytic A. hiratsukae and also exhibited antimicrobial and photocatalytic activities that can be used in environmental applications.

Recently, the plant extract mediated green/bio-synthesis of Ag NPs has been applied as the photocatalyst in the reduction/degradation of CR [22,23]. Our synthesized NPs reduction time was much lowered to compare the other plant extract NPs.…”

Day-to-day increasing in the usage of organic dye and disposed waste has increases the environmental pollution. So there is an emergency need to removal of toxic dyes solution itself non-toxic. In the present work, green synthesis of silver nanoparticles (Ag NPs) from silver ions using the reducing and capping agent of Millingtonia hortensis leaf broth. UV-Vis absorbance spectral value at 423 nm was confirmed the product of Ag NPs. X-ray diffraction (XRD) analysis and selected area electron diffraction (SAED) pattern was confirm the crystalline nature of metallic silver. High resolution transmission electron microscope (HRTEM)analysis morphology of images identified the spherical shape particles with sizes from 20 to 50nm. The product of Ag NPs was applied as photocatalyst in the reduction/degradation of Congo red in the presence of NaBH4 under different experimental conditions to confirm the pseudo first order kinetics. The Ag NPs was good photocatalyst in the reduction/degradation of Congo red within 14 min.

“…The AgNPs (11-15 nm) having globular shape prepared using Amaranthus gangeticus Linn leaf extract as substrate showed 100% degradation in 15 min in the presence of sunlight [101], whereas in the same time CR was reduced to phenyl benzene and sodium(4amino-3diazeneyl-naphthalene)-1sulfonato as schematically shown in figure 9 which are the reduced form of CR using AgNPs prepared from Terminalia arjuna leaf extract in the presence of NaBH 4 with 92% efficiency [94]. CR was degraded completely to colorless form in 24 min using AgNPs synthesized from the extract of Simarouba glauca oilseed meal in the presence of NaBH 4 [91]. It was also seen that even though the size of the nanoparticle is small i.e., 5 nm, the degradation took a longer time when compared to a normal trend, hence this is not the only factor that improves degradation efficiency.…”

Silver nanoparticles (AgNPs) have received a lot of interest for their several applications, including their remarkable potential as photocatalysts for organic dye degradation. This research thoroughly investigates the efficacy of ecologically friendly, green-synthesized AgNPs in the treatment of synthetic dye-contaminated wastewater. The synthesis of AgNPs from various biological substrates is investigated, emphasizing their economic viability, significant conductivity, and considerable biocompatibility. The improper disposal of synthetic dyes in wastewater poses severe environmental and health risks due to their non-biodegradable nature and persistent chemical features. In response to this challenge, this review paper investigates the capability of AgNPs to serve as effective photocatalysts for degrading a range of organic dyes commonly found in industrial effluents. Specific dyes, including Aniline Blue, Congo Red, Nitrophenol, Methylene Blue, and Malachite Green, are studied in the context of wastewater treatment, providing insights into the efficacy of AgNPs synthesized from diverse biological sources. The review sheds light on the photocatalytic degradation methods used by green-synthesized AgNPs, shedding light on the transition of these synthetic dyes into less hazardous compounds. It also delves into the toxicity aspect of the AgNPs and its possible remediation from the environment. The ecologically friendly synthesis procedures investigated in this work provide an alternative to traditional methods, highlighting the importance of sustainable technologies in solving modern environmental concerns. Furthermore, a comparative examination of various biological substrates for AgNPs synthesis is presented, evaluating their respective dye degradation efficiencies. This not only helps researchers understand the environmental impact of synthetic dyes, but it also directs them in choosing the best substrates for the production of AgNPs with enhanced photocatalytic activities.
