Patterned electrodes improve hydrogen production efficiency by controlling bubble spacing

Researchers have discovered how bubble spacing on patterned electrodes impacts hydrogen production efficiency. The study used silicon electrodes with tiny cavities to control bubble formation during electrolysis, revealing that closer cavities lead to more frequent, smaller bubble detachment and reduced gas buildup. This research, published in Small, aims to enhance green hydrogen production by improving the controllability of electrochemical processes, building on the University of Twente's involvement with the Global Young Academy.
