Abstract

In this paper, we show the development of a LabVIEW algorithm able to apply the delayed feedback control on oscillatory electrochemical reactions. The coupling of the control and the experiments was carried out by a real-time apparatus, measuring the faradaic current and, in sequence, applying a calculated circuit voltage as an analog output. The setup was used to control the oscillatory Cu/Sn electrodeposition dynamics, used as a model-system, and the results clearly demonstrate the control accuracy. Overall, the code may be a great tool for the controlled synthesis of nanomaterials in different oscillatory electrodeposition reactions, as it offers the ability to control the composition and structure of the deposit by fine tuning the dynamic properties.
