Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has been
investigated. Morphological and structural characteristics of this electrode type obtained by various parameters of RC regimes
were examined by the techniques of scanning electron and optical microscopies, while the amount of hydrogen produced during
electrodeposition process was quantified by determination of the average current efficiency for hydrogen evolution reaction. To
optimize the process of formation of the honeycomb-like electrodes, the following parameters of square wave RC regimes were
analyzed: the cathodic current density, the same anodic to cathodic time ratios but various durations of the cathodic and the
anodic pulses, and the various values of the anodic to cathodic time ratios. The minimal amount of hydrogen spent for formation
of the honeycomb-like electrodes with maximal number of holes formed from detached hydrogen bubbles is obtained wi...th the
anodic to cathodic time ratio of 0.50 and duration of the cathodic and anodic pulses of 2 and 1 s, respectively. To explain
formation of the honeycomb-like electrodes of optimal morphological and structural characteristics, the upgraded mathematical
model defining the RC regime in the second range was proposed and discussed.
