N2 - Two zinc porphyrinate‐modified Pt electrodes form the essential part of a very promising solar energy conversion system in which ultimately water is reduced to hydrogen. The Na2 salt of ethylenediaminetetraacetic acid (H4 EDTA) is employed as sacrificial electron donor; methyl viologen (MV2⊕) functions as electron transfer agent and platinized TiO2 as reduction catalyst. Decisive is that the anode is coated with an n‐semiconducting porphyrinate (zinc 5‐(4‐pyridyl)‐10,15,20‐tritolylporphyrinate) and the cathode with a p‐semiconducting porphyrinate (zinc 5,10,15,20‐tetra(4‐pyridyl)porphyrinate). Currently, the yields of H2 still lie in the μmol range.
