Systemic Approach for Numerical Modelling and Simulation of Koutecky-Levich equation for NADH electrocatalytic oxidation at graphite electrodes modified with a polymeric phenothiazine

摘要

Numerical modelling and simulation of Koutecky-Levich equation for NADH electrocatalytic oxidation at graphite electrodes modified with a polymer of phenothiazin formaldehyde (PPF) was performed. There were obtained the second order electrocatalytic rate constants (k{sub}(obs, [NADH]=0)) from rotating disk electrode experiments, at various concentrations of NADH and phosphate buffer with different pH values.
