Bimetallic Cluster Metal‐Organic Frameworks for Rapid Photocatalytic Water Splitting to Produce Hydrogen

A core challenge in photocatalytic water splitting for hydrogen production, as a clean method of hydrogen fuel generation, lies in simultaneously achieving efficient hydrogen production and long‐term stability of catalysts. Herein, we report the successful synthesis of a novel bimetallic cluster‐based metal‐organic framework (MOF) exhibiting exceptional performance for visible‐light‐driven photocatalytic hydrogen production. This unique MOF catalyst demonstrates a remarkably high hydrogen evolution rate of 20,778.7 μmol g −1 h −1 under visible‐light irradiation, significantly surpassing many MOF photocatalysts. Crucially, the MOF exhibits outstanding stability, maintaining its high catalytic activity over multiple reaction cycles without significant degradation. The synergistic effects within the bimetallic clusters and sensitively light‐responsive linkers are regarded as the key contributors to both the enhanced efficiency and remarkable durability. This work presents a highly promising and stable MOF photocatalyst for efficient solar energy harnessing towards clean hydrogen fuel generation.
