“…Similar findings were discussed where MB dye was subjected to photodegradation without the presence of the biosynthesized AgNPs. Negligible MB dye decolorization and very low photocatalytic rate were observed (Ji et al, 2018;Ajay et al, 2022). Whereas some studies reported no appreciable decrease in the MB concentration was observed in the absence of the biosynthesized AgNPs prepared (Singh et al, 2020;Mehwish et al, 2021).…”

Water pollution is a chronic problem affecting the entire ecosystem. To partly remediate water pollution, wastewater treatment prior to disposal must be done regularly. Here, the photocatalytic degradation of methylene blue (MB) dye was assessed using R. rosifolius Linn (also known as sampinit) aqueous fruit extract silver nanoparticles (SAFE-AgNPs). In this study, the SAFE-AgNPs were utilized to remediate wastewater contaminated with methylene blue (MB) dye which is harmful to the environment, aquatic and human lives. As previously described, SAFE-AgNPs were synthesized via a simple ‘one-pot’ approach. SAFE-AgNPs were assessed for their photocatalytic reduction of MB dye following sunlight or LED irradiation. Kinetic adsorption models were employed to determine the adsorption uptake of MB by SAFE-AgNPs. Photocatalytic degradation of methylene blue by SAFE-AgNPs was achieved under sunlight and LED irradiations at 98.8% and 97.6%, respectively. These results on the photocatalytic degradation of MB by SAFE-AgNPs may offer a potential strategy in wastewater treatment.

“…Conventional methods available for the treatment of dye effluents from various industries often result in the formation of toxic byproducts. However, AgNPs can effectively be used in the total degradation of azo dyes without yielding toxic waste products (Ajay et al, 2022).…”

The biological synthesis of nanoparticles using plants or microorganisms has gained attention in the recent past, mainly due to its eco-friendly nature and because they can be used in a vast variety of fields such as medicine, agriculture and textiles. The current study focuses on the green synthesis of silver nanoparticles (AgNPs) using five varieties of Cordyline fruticosa (candy cane, waihee rainbow, exotica, pink cascade and pink diamond) leaves, and assessing their antioxidant, photocatalytic and antimicrobial activities. SEM analysis of pink cascade-AgNPs shows they are spherical and in the range of 40-50nm. Band gap energy calculations reveal that synthesized AgNPs can act as semiconductors. Total flavonoid content, total phenolic content and total antioxidant capacity were analyzed and the DPPH-free radical scavenging assay was performed. These showed that AgNPs had higher antioxidant activity compared to aqueous extracts. The antibacterial activity of AgNPs and aqueous extracts was assessed using cultures of Escherichia coli and Staphylococcus aureus. Extracts and AgNPs showed better bactericidal effect on S.aureus. Photocatalytic activity of synthesized AgNPs was assessed using malachite green as a model dye and significant degradation of the dye was observed when AgNPs were added together with catalyst NaBH4. According to the results obtained from this study, it can be seen that AgNPs synthesized using Cordyline fruticosa have potential in different aspects including treatment of free-radical mediated diseases, overcoming antibiotic resistance, treatment of bacterial diseases and overcoming environmental pollution.
