Diagram illustrating a three-dimensional nanorod catalytic electrode system based on nickel for accelerated release of hydrogen bubbles

Caption

The team created a porous nickel catalyst material featuring a nanorod protrusion structure, incorporating efficient three-dimensional pore channels and superaerophobic surface wettability. This design aims to facilitate the rapid separation of hydrogen bubbles from the catalyst surface. The outcome is a significant enhancement in the efficiency of hydrogen production within the water electrolysis system when compared to traditional bulk thin film-shaped catalyst electrodes.
