Eco-Nanotechnology for Renewable Energy: Green Synthesis of Ag Nanoparticles for Enhanced Bioethanol Production

This study presents an eco-friendly approach for synthesizing silver (Ag) NPs using natural extracts from Mentha spicata leaves. The primary objective was to explore the potential of these green synthesis methods for enhancing bioethanol production. Various analytical techniques including UV-Vis spectroscopy, X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, and Scanning Electron Microscopy (SEM), were employed to characterize the size, structure, surface morphology, and composition of the synthesized nanoparticles. Key findings revealed UV-Vis spectra absorption peaks at ۴۲۵ nm for Ag (NPs), indicating the effectiveness of plant extracts as reducing agents. FTIR analysis identified significant stretching peaks associated with limonene compounds, confirming the involvement of natural compounds in the synthesis. XRD patterns indicated that Ag (NPs) displayed a face-centered cubic structure. SEM images showed that Ag (NPs) averaged ۶.۴۵ nm in size. Finally, Ag (NPs) have an influence on bioethanol production, microbial growth and enzyme activity in a concentration dependent manner. Low and moderate concentrations (۱-۳۰ mg/L) attended increases in all three outcomes, preferring growth to the maximum at the ۳۰ mg/L. Greater concentrations (>۳۰ mg/L) yield microbial cytotoxic effects and population reduction, which ultimately lead to decreased enzyme activity and bioethanol production. These results indicate that the nanoparticles that we synthesized from renewable sources have significant potential as catalysts to improve bioethanol production. Given their remarkably catalytic activities and their clearly defined morphologies, these have potential for renewable biofuels applications.
