Biosynthesis of AG:C20H9CLO5AG:Carbon using Opuntia Cochenillifera Fruit Extract and its Electrochemical Study for Antioxidant Applications

Dichlorofluresceinic acid (C20H10ClO5) has been used in Fazan’s method for argentometric analyses. Present work describe the cost effective, bio-synthesis of silver:silver dichlororflureceinate (Ag:C20H9ClO5Ag) and preparation of Ag:C20H9ClO5Ag:C composite for electrochemical study. XRD, FTIR and UV-Vis were used to confirm the formation of material. TEM demonstrates the formation of spherical and rod like structures with variable sizes ranging from 21.40 to 47.21 nm. Electrochemical analysis of the prepared composite has been carried out using cyclic voltammetry (CV) in 0.5 M 20 ml H2SO4. CVs were carried out at high scan rates 50 to 5000 mVs-1 in the potential window – 0.6 to 0.9 V. The prepared composite show no oxidation peak at all but the reduction peak becomes more prominent with scan rate indicating the applicability of the prepared material as the antioxidant against the anionic radicals in atmosphere.
