Summary: | Biogenic silver nanoparticles were synthesized using novel Terminalia bellerica kernel extract. Optimal synthesis of silver nanoparticles was achieved at 0.016 mg/mL kernel extract and 2.0 mM silver nitrate concentrations under ambient conditions. Silver nanoparticles were characterized by ultraviolet–visible absorption spectroscopy, transmission electron & scanning electron microscopy, energy dispersive X-ray analysis, X-ray diffraction, and Fourier transform infrared spectroscopy. Synthesized silver nanoparticles displayed innate catalytic reduction of organic pollutants such as 4-nitrophenol, methylene blue, eosin yellow and methyl orange. Results revealed that among all the pollutants, nanosilver exhibited higher reduction of 4-nitrophenol than others and reaction was found following the pseudo-first order kinetics. An artificial neural networks (ANNs) model based on experimental data was developed to predict the catalytic performance of nanosilver. Good correlation between ANN model based results and experimental data indicated that it could be used to forecast the catalytic performance and hence extent of pollutant reduction at various catalyst concentrations.
