Herein, Sargassum coreanum (marine algae)-mediated silver nanoparticles (AgNPs) were successfully synthesized by a simple reduction method. The synthesized AgNPs were characterized using ultraviolet-visible spectroscopy, attenuated total reflection Fourier transformed infrared spectroscopy, X-ray diffractometry, field emission scanning electron microscopy (FESEM) with energy-dispersive X-ray (EDX) spectroscopy, and high-resolution transmission electron microscopy (HR-TEM) analysis. The acquired colloidal AgNPs were strongly absorbed around 420 nm and displayed brown color under visible light. The XRD pattern of AgNPs exposed their face-centered cubic geometry along with crystalline nature. The HRTEM images of synthesized AgNPs confirmed the mean particle size of 19 nm with a distorted spherical shape, and the calculated interlayer distance (d-spacing value) was about 0.24 nm. Further, the catalytic degradation of methylene blue using sodium borohydride and AgNPs was monitored using UV–vis spectroscopy. The result revealed that AgNPs performed as a superior catalyst, which completely degraded MB in 20 min. The rate constant for MB degradation was calculated to be 0.106 min−1, demonstrating that the marine algae-mediated AgNPs had outstanding catalytic activity. This approach is easy and environmentally benign, which can be applied for environmental-based applications such as dye degradation and pollutant detoxification.

In pursuit of greener nanoscale research, the utilization of the reductive potency of a common byproduct of food-processing industry, i.e., orange peel, has been researched to prepare “green” silver nanoparticles (AgNPs). The synthesized AgNPs were characterized by UV-Vis spectroscopy, dynamic light scattering, and scanning electron microscopy. The results confirmed that silver nanoparticles were formed at the investigated concentrations of Ag+ (0.25–6.0 mmol/L) during 5–10 minutes, at ratio AgNO3 : extract (mL) = 1 : 1, and at 75°C. From the SEM images, the silver nanoparticles are found to be almost spherical. Powder XRD results reveal that Ag nanoparticles had a face-centered cubic crystal structure. The zeta potential value for AgNPs obtained was −21.7 mV, indicating the moderate stability of synthesized nanoparticles. The effect of pH on nanoparticle synthesis has been determined by adjusting the pH of the reaction mixtures. The catalytic effectiveness of the prepared green catalyst, AgNPs, has also been investigated in catalytic degradation of methylene blue (MB) dye. The catalytic degradation reaction under solar irradiation was completed (99%) within 35 min, signifying excellent catalytic properties of silver nanoparticles in the reduction of MB.
