Abstract
Abstract Ammonia borane (AB) with 19.6 wt % H 2 content is widely considered a safe and efficient medium for H 2 storage and release. Co‐based nanocatalysts present strong contenders for replacing precious metal‐based catalysts in AB hydrolysis due to their high activity and cost‐effectiveness. However, precisely adjusting the active centers and surface properties of Co‐based nanomaterials to enhance their activity, as well as suppressing the migration and loss of metal atoms to improve their stability, presents many challenges. In this study, mesoporous‐silica‐confined bimetallic Co−Cu nanoparticles embedded in nitrogen‐doped carbon (Co x Cu 1−x @NC@mSiO 2 ) were synthesized using a facile mSiO 2 ‐confined…
