“…On the other hand, methylene blue, as a colouring agent with environmental impacts, can be reduced to leucomethylene blue through a catalytic process [28]. Similarly, silver nanoparticles exhibit notable catalytic activity in the reduction of methylene blue [29]. This conversion has the potential to produce compounds that are more environmentally friendly.…”

Drymoglossum piloselloides is one of the epiphytic plants that is commonly found in Southeast Asia region. In this study, the ethanol extract of D. piloselloides plant has been used in the green synthesis of silver nanoparticles. The synthesized silver nanoparticles were characterized by ultraviolet-visible (UV-Vis) spectrophotometry, X-ray diffraction (XRD),Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM) measurements. The UV-Vis spectrum of silver nanoparticles showed a maximum wavelength at 453 nm. The XRD measurement showed the silver nanoparticles peaks at 38.38°, 44.60°, 64.76°, and 77.62°. The FTIR spectra provided evidence of the interaction between silver and chemicals in the plant extract as a weak signal at 682 cm-1. Meanwhile, TEM revealed an average size of 12.63nm. The synthesised silver nanoparticles were utilised for the reduction of 4-nitrophenol with a conversion percentage of up to 100% with a reduction reaction rate constant of 7.104 s-1. In addition, methylene blue was also successfully reduced with the synthesised silver nanoparticles as the catalyst with a reduction reaction rate constant (k) of 21.150 s-1. This study highlights the superior advantage of utilizing ethanolic extract of D. piloselloides to prepare silver nanoparticles with promising catalytic reduction purposes.

Pharmaceutical substances, a pill for every ill, have become a sweet poison by remarkably boosting the global economy as well as human and animal wellness and at the same time causing environmental pollution, especially in the aquatic ecosystem, and this has led to a fatal diminution in the availability of clean water and upsurge in water insecurity. Notably, traditional techniques and materials have been employed to clean up pharmaceutical pollutants (PP) from aquatic bodies; however, they have come under controversy because they require hazardous chemicals and cannot fully mineralize stubborn PPs. Interestingly, the photocatalytic degradation approach employing eco‐benign biosynthesized nanoparticles (BNP) is an avant‐garde practice and has shown to be an eco‐sustainable method that can fully mineralize PPs into harmless molecules. Thus, this study critically explores the application of BNPs for the photocatalytic degradation of PPs. The review revealed that the greatest degradation efficacy of BNPs was greater than 80% in most cases, and that the least amount of time required was around 10 min. In addition, the oxygen‐containing functional groups found in the biological sources used for the fabrication of BNPs contributed to the supremacy of •OH and O2• radicals in the degradation operation. Also, the photocatalytic degradation kinetic data was well modeled by pseudo‐first order, and this indicates that •OH was more involved in the PPs degradation operation than O2•. Moreso, BNPs have excellent reusability potential (>5 rounds) while maintaining inherent structural integrity. Techno‐economic analysis revealed that BNPs are cost‐effective, costing about $1.5/1,000,000 mL of pharmaceutical wastewater on average.
