Despite the adverse effects of H2 bubbles adhering to catalyst's surface on the performance of water electrolysis, the mechanisms by which H2 bubbles are effectively released during the alkaline hydrogen evolution reaction (HER) remain elusive. In this study, a systematic investigation on the effect of nanoscale surface morphologies on H2 bubble release behaviors and HER performance by employing earth‐abundant...
Hydrogen Evolution Reaction
In article number 2305844, Jaerim Kim, Yong‐Tae Kim, Jong Kyu Kim, and co‐workers explore the impact of nanoscale surface morphologies on the release behavior of H2 bubbles and electrochemical hydrogen evolution reaction (HER) performance by introducing surface morphology‐controlled Ni catalysts. The highly porous Ni catalyst, composed of an array of Ni nanorods, exhibits...
