Figure 4

Light-driven water photoelectrolysis with production of H2 at the NiO photocathode and O2 at the TiO2 photoanode. The scheme depicts a PEC in which both oxide electrodes are sensitized with supramolecular assemblies with PS, i.e., the photosensitive moiety of the assembly, and Cat, i.e., the catalytic center of the assembly, which execute a process of et upon light excitation of PS.
