Abstract


In the present work, we report on the biosynthesis of silver nanoparticles (AgNPs) using leaf extract of Convolvulus pluricaulis (Shankapushpi, bindweed) at room temperature. Synthesis of AgNPs is carried out by incubating the leaf extract in presence of AgNO3. Formation of AgNPs is confirmed by the appearance of a prominent surface plasmon resonance band in the UV-visible spectrum at 420 nm. The biosynthesized AgNPs are characterized by powder X-ray diffraction (XRD) studies, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermo gravimetric analysis (TGA) and differential thermo gravimetric (DTG) analysis. Further, the biosynthesized AgNPs are investigated for their catalytic, electrocatalytic and phenol remediation properties. The investigations revealed that the biosynthesized AgNPs excel in their respective applications. Based on the results, present study concludes that AgNPs can be biosynthesized using leaf extract of Convolvulus pluricaulis and further can be employed for applications in electrochemical sensing, dye degradation and phenol remediation.
