Figure 5

Left: depiction of the photoelectroactive material consisting of p-type NiO nanoparticles decorated with the dye-sensitizer coumarin 343 (PS) and the biomimetic Fe-Fe catalyst (Cat) directly anchored on NiO through the phosphonate group. Right: temporal profiles of the current density associated to H2 generation as a function of the light-switching time when Fe-Fe Cat [1] is not included (black profile), and when is anchored (red profile).
