Title: Electrochemical synthesis of new Bi(III) complex by anodic oxidation of Bi in an aqueous solution of 4-toluenesulfonic acid Keywords: Anodic layers, Anodic oxidation, Bismuth compounds, Electroc Abstract: The anodic behaviour of bismuth in aqueous p-toluenesulfonic acid at three different concentrations and in the potential range from 0 to 1.0 V is studied. A significant amount of white precipitate on the bismuth surface is synthesized at selected potentials. The morphology and elemental composition of the anodic layers are observed using SEM and EDS, respectively. The composition and crystallinity of the product at 1.0 V are determined using FT-IR, ICP, XPS and XRD analytical methods. The composition of the anodic product is compared with that of an already known product synthesized via a chemical reaction between Bi2O3 and p-toluenesulfonic acid. The results show that the anodic product has a composition of [Bi6O4(OH)4](C7H7SO3)6. Hence, this product can be prepared via electrochemical synthesis by the potentiostatic polarization of bismuth at 1.0 V. References Issue
