Electrodeposition is regarded as one of the promising approaches to fabricate catalysts for green energy technologies, such as hydrogen production and CO2 reduction. The better one perceives the underlying relationships between the catalyst morphology and the contributing parameters to it, the more likely it would be to know how to fabricate given catalysts, based on the need!
It is already known that by increasing the overpotential, nanoparticles of higher island density, Np, deposit on the substrate; the nucleation density follows an exponential relationship with the actual deposition overpotential. Indeed, when ln Np is plotted versus overpotential, the points will form a line with a given slope. That is a good start! What about the substrate characteristics, such as surface energy?! In this master project, an answer to this question is sought. It is aimed to see how surface characteristics can change the position of the lines, which can be regarded as the substrate’s platability. Using galvanostatic polarization and SEM observations, nucleation and growth kinetics on different substrates are compared and analysed.
