Selenium Modification Induces Rapid Microbubble Detachment, Enabling Highly Efficient Water Electrolysis for Hydrogen Production
Highly efficient and stable oxygen evolution reaction (OER) electrocatalysts are critical to the performance of anion exchange membrane water electrolysis (AEM-WE) devices. However, at ampere-level high current densities, the accumulation and retention of oxygen bubbles lead to localized mass-transfer limitations, blockage of active sites, and stress concentration at the electrode interface, si...
