Hybrid polyoxometalate-porphyrin copolymeric films are obtained by the electro-oxidation of zinc octaethylporphyrin (ZnOEP) and zinc 5,15-dipyridinium octaethylporphyrin (5,15-ZnOEP(py)(2)(2+)) in the presence of the polyoxometalate [MnMo6O18{(OCH2)(3)CNHCO(4-C5H4N)}(2)](3-) (Py-POM-Py). These films allow the photocatalytic reduction of (Ag2SO4)-S-I under visible irradiation in air in the presence of propan-2-ol at the 2D interface between water and the copolymeric films. The formation of metallic Ag-0 nanowires and triangular nanosheets is observed.
