Abstract
AbstractInorganic 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.

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 Inorganic chemical cells (iCHELLs) approach for catalysis, where the structure, compartmentalisation and variation in possible components could be utilised to approach a wide range of reactions
By constructing iCHELLs composed of [PW12O40]3À or [SiW12O40]4À polyoxometalate (POM) anions and MV2+ cations, we were able to construct a system in which efficient and sustained hydrogen evolution reaction (HER) was driven by anisotropic and hierarchical electron transfer across the membrane, see Figure 1
