摘要

Abstract

The application of homogeneous electrocatalytic reactions in energy storage and conversion has driven surging interests of researchers in exploring the reaction mechanisms of molecular catalysts. In this paper

homogeneous electrocatalytic reaction between hydroxymethylferrocene (HMF) and L-cysteine is intensively investigated by cyclic voltammetry and square wave voltammetry for which

the second-order rate constant (

) of the chemical reaction between HMF

and L-cysteine is determined

via

a 1D homogeneous electrocatalytic reaction model based on finite element simulation. The corresponding

(1.1 (mol·m

) is further verified by linear sweep voltammograms under the same model. Square wave voltammetry parameters including potential frequency (

)

increment (

step

) and amplitude (

) have been comprehensively investigated in terms of the voltammetric waveform transition of homogeneous electrocatalytic reaction. Specifically

the effect of potential frequency and increment is in accordance with the potential scan rate in cyclic voltammetry and the increase of pulsed potential amplitude res

ults in a conspicuous split oxidative peaks phenomenon. Moreover

the proposed methodology of

prediction is examined by hydroxyethylferrocene (HEF) and L-cysteine. The present work facilitates the understanding of homogeneous electrocatalytic reaction for energy storage purpose

especially in terms of electrochemical kinetics extraction and flow battery design.
