Development of a Minimal Photosystem for Hydrogen Production in Inorganic Chemical Cells

Inorganic chemical cells (iCHELLs) are compartment structures consisting of polyoxometalates (POMs) and cations, offering structured and confined reaction spaces bounded by membranes. We have constructed a system capable of efficient anisotropic and hierarchical photo‐induced electron transfer across the iCHELL membrane. Mimicking photosynthesis, our system uses proton gradients between the compartment and the bulk to drive efficient conversion of light into chemical energy, producing hydrogen upon irradiation. This illustrates the power of the iCHELL approach for catalysis, where the structure, compartmentalisation and variation in possible components could be utilised to approach a wide range of reactions.

Ein System für den hierarchischen photoinduzierten Elektronentransfer durch die iCHELL‐Membran wurde konstruiert. Es nutzt Protonengradienten für die effiziente Umwandlung von Licht in chemische Energie und produziert unter Lichteinfall Wasserstoff.
