Contact line dynamics modulated by electrode roughness determines bubble detachment size
Facilitating bubble detachment during water electrolysis significantly improves process efficiency. This study investigates hydrogen bubble contact line dynamics on nickel electrodes through high-speed imaging, identifying two distinct wetting modes: sliding and rolling. Surface roughness governs bubble detachment size by mediating the relative weights between these modes.
