A comparative investigation of the adsorption of aliphatic alcohols on a smooth platinum electrode at high and low anodic potentials in acidic and alkaline solutions has been carried out with the aid of a potentiodynamic method. The data obtained point out that the mechanism for the adsorption of alcohols at high anodic potentials differs from the mechanism for the adsorption of alcohols with dehydrogenation at low anodic potentials. Normal aliphatic alcohols are widely employed in many processes for the electrochemical synthesis of organic compounds. The adsorption behavior of alcohols on smooth and platinized platinum has been studied by radiochemical, potentiodynamic, and other electrochemical methods. In this work, investigations were carried out on a model 04 PO-5122 pulse potentiostat with the use of the complex potentiodynamic pulses A, B, C, and D, whose forms are presented in respective figures.
