Deciphering Structure-Bubble-Mass Transfer Relationships in Water Electrolysis Through Electrode Morphology Regulation. [PDF]

Adv Sci (Weinh)
Electrode morphology is shown to govern oxygen‐bubble dynamics and interfacial mass transfer during water electrolysis. Positive‐curvature nanoneedles promote rapid release of small bubbles, sustain electrolyte renewal, and minimize mass‐transport losses, whereas flat and concave architectures increasingly retain bubbles.
