Hybrid polyoxometalate–porphyrin copolymeric films can be obtained by the electro-oxidation of 5,15-ditolyl porphyrin (H$_{\mathbf{2}}$T$_{\mathbf{2}}$P) and zinc-$\beta $-octaethylporphyrin (ZnOEP) in the presence of the Lindqvist-type polyoxovanadates $\mathrm{TBA}_{2}[\mathrm{V}_{6}\mathrm{O}_{13} \lbrace (\mathrm{OCH}_{2})_{3}\mathrm{CNHCO} (4\mbox {-}\mathrm{C}_{5}\mathrm{H}_{4}\mathrm{N})\rbrace _{2}]$ (Py-V$_{\mathbf{6}}$O$_{\mathbf{13}}$-Py). The photocatalytic properties of these films have been studied for the reduction of silver and platinum ions. In these hybrid materials, porphyrins can be excited by visible light and then play the role of photosensitizers able to give electrons to the polyoxovanadates catalysts.
