The particular concern was that most of these oxygen evolving homogeneous catalysts decomposed irreversibly with repeated use and that the unidentified decomposition products might often act as oxygen evolving catalysts ... 

Suitable oxygen evolving catalysts (OECs) must respond to the requirements of (1) availability of different oxidation states, (2) ability of transferring protons, and (3) possibility to form metallo-oxo species, responsible for the oxygen-oxygen bond formation.

Fig. 9 Photosensitizer (P) - oxygen evolving catalyst (OEC) dyad supported onto a nanos-tructured material, deposited onto an electrode. The resulting photoanode is then assembled with a cathode and a membrane, yielding a device for artificial photosynthesis (i.e. an artificial leaf).
