Abstract

Language:

The study analyzed copper powder particles formed through electrolysis under varying amounts of evolved hydrogen. The objective was to explore the relationship between the morphology of the particles and the quantity of hydrogen produced during the electrodeposition process. Using scanning electron microscopy (SEM), the research examined two distinct types of particle morphologies resulting from differing hydrogen quantities. One type of particle, formed with low hydrogen production, displayed corncob-like structures, while the other exhibited a cauliflower-like morphology when sufficient hydrogen was released to alter the hydrodynamic conditions near the electrode. Both particle types comprised agglomerates of copper grains, differentiated solely by their size. The findings indicated that the grain size was influenced by the overpotential during electrodeposition, showing a trend towards stabilization as the overpotential increased. Overall, the results demonstrated a clear link between the electrochemical conditions and the resulting particle morphology, emphasizing the importance of hydrogen evolution in the electrodeposition process.
