Reconstruction Of Distributions Of Nanoparticles Or Electroactive Nano-Components In Electrochemical Arrays Based On Chronoamperometric Data, Alexander Oleinick, Oleksii Sliusarenko, Irina Svir, Christian Amatore

Journal of Electrochemistry

The main scope of this work was to elaborate and test a simple mathematical and numerical procedure for reconstructing the probability density distributions f(ρ) characterizing the distribution of electroactive or electrocatalytic nano-components present or deposited on the electrochemically-inert surface of a planar conductor based on the time-dependent chronoamperometric responses of the corresponding electrochemical array. The mathematical and numerical validity of the procedure was established for three types of arrays (one periodical, two involving random dispersions) involving near-spherical nano-components dispersed on a flat surface. Indeed, altogether, these three types represent most 2D-experimental electrochemical nano-arrays used for analytical or electrocatalytic purposes. This …
