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.
