Sustainable synthesis and characterization of silver nanoparticles through Juncus acutus flowers and evaluation of their ability to detect NO2 and NH3 gases
Year: 2025
Type: article
Abstract: In this effort, the Juncus acutus plant's flowers were used to create silver nanoparticles (AgNPs). Using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray (EDX), the characteristics of the prepared silver nanoparticles were evaluated. The size of the silver nanoparticles was 38.40 nm. At various temperatures and times, the silver nanoparticles were assessed as gas sensors for the gases NO 2 and NH 3 . At 100°C, the highest sensitivity response to NO 2 gas was 15.09%. However, in the case of the NH 3 gas, the highest sensitivity response was 25% at 200°C. For NO 2 , the sensor displayed the smallest response and recovery times at various temperatures: 19.71s at 300°C and 33.3s at 100°C, respectively, and for NH 3 gas, 16.74s at 200°C and 20.25s at 300°C, respectively. These outcomes highlight the sensor's exceptional response and recovery abilities.
