Preparation Of Modified Surfaces Based On Tannic Acid and Carbon Nanotubes and Investigation Of Their Electrochemical Properties

Year: 2024

Type: article

Abstract: This study focuses on the electrochemical investigation of modifiers and their components that can provide the easiest and most sensitive results for electrochemical sensors. For this purpose, a nanocomposite of tannic acid and carbon nanotubes with extraordinary properties was obtained. The nanocomposite and its components were immobilized on glassy carbon electrode surfaces by the drop-drying technique. The morphological and electrochemical properties of the nanocomposite and its components were examined by scanning electron microscopy and cyclic voltammetry techniques. The surfaces modified with the nanocomposite and its components exhibited different electrochemical behaviors. Tests performed in ferricyanide, ferrocene, ruthenium hexamine (III) chloride, and ferricyanide/ferrocyanide probes showed that the nanocomposite-modified surface exhibited the best voltammetric behavior. Scan rate and pH studies showed that the nanocomposite-modified surface catalyzed electron transfer more and increased the active surface area.
