Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A composite proton‐reducing catalyst Hy@MCM‐41 was created by using a hydrophobic [Fe‐Fe]‐hydrogenase mimic (Hy) incorporated into the K⁺‐exchanged molecular sieve MCM‐41. Hy acts as the active site to generate H₂ by reducing H⁺, and MCM‐41 provide a large surface area to maintain the dispersion of Hy and to prevent aggregation and precipitation. Hy@MCM‐41 was successfully applied to the light‐induced hydrogen production in pure water with an iridium compound [Ir(ppy)₂bpy]Cl and triethylamine (TEA) as the photosensitizer and the sacrificial electron donor, respectively, exhibiting good stability and catalytic activity. The present study provides a general strategy for the application of water‐insoluble catalysts in pure water by using mesoporous molecular sieves.</p> </abstract>
