In-situ Synthesis of Bos taurus indicus Urine Assisted Ag/rGO Nanocomposite for Nitroarenes Reduction and Biological Activity

Abstract

In order to effectively purify drinking water or wastewater, harmful organic contaminants like nitroarenes must be removed from water systems. In this context, the present study developed a unique bio-mimetic, in-situ synthesis of Ag/rGO nanocomposite. We employed Bos taurus indicus urine to make Ag/rGO nanocomposite in an environmentally friendly, economical, and sustainable manner. Through the use of DLS, FE-SEM, FT-IR, Raman, TGA-DSC, XRD, and Zeta Potential analysis, the morphological, elemental, and structural characterization were completed. 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 nanocatalyst were assessed towards the catalytic reduction of several environmental pollutants such as 2,3 & 4-nitroaniline and 4-nitrophenol. For 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.
