Abstract
A study is performed of the electrocatalytic properties of 4,4'-bipyridine in the presence of acids of different natures (HBF4, HClO4, TsOH, CF3COOH). It is shown that pK acids are a key factor influencing the mechanism of the reactions taking place. The obtained electrochemical and electrocatalytic data are used to investigate the main mechanisms of the electrocatalytic production of molecular hydrogen, depending on the pK of the relevant acids. The same data are employed to calculate their thermodynamic and kinetic parameters.
