Abstract
The present study developed a unique bio-mimetic, in-situ synthesis of catalytically and biologically active Ag/rGO nanocomposite. Herein, we employed Bos Taurus Indicus urine to synthesize Ag/rGO nanocomposite in an environmentally benign, economical, and sustainable manner. The elemental composition, morphology and structure were analyzed through advanced characterization techniques such as X-RD, DLS, Zeta potential, FE-SEM, FT-IR, Raman spectroscopy, TGA-DSC etc. Investigations were conducted into the catalytic effectiveness of prepared nanomaterials for diverse nitroarenes reduction. Then, using NaBH4 at 25oC, the catalytic roles of Ag and Ag/rGO Nano-catalyst were assessed towards the catalytic reduction of several environmental pollutants such as 2, 3 & 4-nitroaniline and 4-nitrophenol. To test their catalytic performance, bio-mimetically synthesized Ag NPs were thermally treated at 200 °C and compared to Ag/rGO nanocomposite. The antibacterial and antioxidant properties of as-prepared nanomaterials were investigated in this study. The finding signifies the importance of such nanocomposites in medicinal chemistry and antibacterial creams for external use.
