Electrochemical behavior of different types of alumina
Abstract
This work presents the investigation of electrochemical properties of three alumina samples with different structure and crystal water content. The samples were characterized by XRD and FTIR-ATR analysis, confirming the presence of trihydrate, monohydrate and anhydrous alumina. The samples were used as modifiers of carbon paste electrodes. Their electrochemical behavior toward ferricyanide/ferrocyanide redox probe was evaluated by electrochemical impedance spectroscopy and cyclic voltammetry. The electrochemical behavior toward ruthenium hexamine redox probe was investigated by cyclic voltammetry. The response toward quinone/hydroquinone redox probe was evaluated in buffered and unbuffered solution by cyclic voltammetry. It was found that the surface chemistry of investigated samples influenced their electrochemical properties.
