Electrode Surface Coverage with Deposit Generated Under Conditions of Electrochemical Nucleation and Growth. A Mathematical Analysis

Abstract The theory of the diffusion limited electrochemical nucleation and growth a deposit consisting isolated 3D hemispherical nuclei has been re-analysed. analysis focuses on widely discussed model which assumes formation “diffusion zones” around growing nuclei. It proposed in literature that deposit-free fraction surface area substrate can be directly calculated from coverage with zones”. aim this work is to analyse whether such an approach applied for This accomplished by evaluation equations describe radii at various stages deposition process. formulae allow determining deposit. This, turn, allows simulating analysing faradaic currents due other than electrodeposition reactions take place surface. Both instantaneous progressive modes are influence type outlined. A comparison approaches reported indicates may not always determined means recalculation Graphical abstract
