WebAug 30, 2024 · The rate-determining step is transferred to the Heyrovsky reaction from the Volmer process. This implies that the HER process may follow the fast discharge reaction (i.e., Volmer reaction) followed by slow desorption reaction (Heyrovsky reaction). The electrochemically active surface area (ECSA) of the samples was calculated from the CV.
