A new strategy for simulation of electrochemical mechanisms involving acute reaction fronts in solution: Application to model mechanisms

The new strategy for adaptive simulation of electrochemical reaction mechanisms described in a previous paper (C. Amatore, O. Klymenko, I. Svir. Electrochem. Commun., (2010), doi:10.1016/j.elecom.2010.06.009) [1] provides an efficient method of obtaining accurate concentration distributions and electrochemical currents. In this paper, this strategy is illustrated and tested more deeply upon simulating several representative classical electrochemical mechanisms involving fast homogeneous comproportionation or disproportionation reactions that pose severe difficulties when simulated by classical finite difference methods including those based on exponentially expanding grids.
