Conjugation of Transmembrane PET with Redox Reactions

As shown in the previous Sections, the transmembrane PET may lead to the generation of energy-rich one-electron reductant and oxidant separated by the membrane (see example in Fig. 3). The final goal in designing the membrane 

For the membrane-separated oxidant and reductant to be involved in the water cleavage process, several thermodynamic, kinetic, steric, etc. conditions should be simultaneously satisfied. 

Second, in order to involve the oxidant and reductant in the multielectron reactions of water oxidation and reduction, one has to introduce appropriate catalysts into the aqueous phases separated by the membrane. 

to provide sufficient rate of water photodecomposition, the high specific rate of the transmembrane PET are needed. In this respect the suspensions of vesicles with a more developed membrane surface are preferable as compared to planar BLMS. 

Fourth, the oxidant and the reductant resulting from the transmembrane PET should not react with the gaseous products of water cleavage (dihydrogen and dioxygen) which can readily permeate through lipid membranes.
