Cover Picture: An [Fe‐Fe]‐Hydrogenase Mimic Immobilized on MCM‐41 for the Photochemical Production of Hydrogen in Pure Water (Chin. J. Chem. 6/2014)

The cover picture shows a convenient approach for the application of water‐insoluble hydrogenase mimics in water. A hydrophobic hydrogenase mimic has been successfully applied to the photochemical production of hydrogen in pure water by immobilization of it into MCM‐41 with an iridium compound [Ir(ppy) 2 bpy]Cl and triethylamine as the photosensitizer and the sacrificial electron donor, respectively. The immobilization stabilizes hydrogenase mimic, which endows the catalytic system good catalytic activity. The present study provides a general strategy for applying hydrophobic artificial catalysts in pure water by using mesoporous molecular. More details are discussed in the article by Li et al . on page 479–484.
