Abstract
Alcohol to aldehyde conversion is a significant industrial process. Herein, we developed the biphasic method for converting the alcohols to aldehydes and ketones in the presence of potassium iodate as an electrocatalytic mediator. This transformation is obtained after 3.5 h at room temperature using the Platinum (Pt) metal electrodes decorated with molybdenum disulphide (MoS2) and Carbon Paste (CP). A thin layer of MoS2 and CP helps to evenly deposit the Pt metal onto the surface, resulting in a significant surface improvement. The electrochemical properties of the modified platinum electrodes were analyzed by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The physicochemical properties of the modified electrodes were studied by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. This method has been applied to the electrochemical oxidation of benzyl alcohol via interphasic in iodate free radicals. The cyclic potentiometric studies showed the electrocatalytic activity of the Pt-MoS2-CP electrode was higher than the Pt–MoS2 electrode in terms of the ability to convert benzyl alcohol to benzaldehyde. High electrocatalytic activity, rapid current response, and stable catalytic activity were all characteristics of the chemically modified electrode.
