Water Oxidation Sensibilized by Tin-Porphyrin

Abstract

A tin meso-tetra(p-sulphophenyl)porphine sodium salt(SnTPPSNA₄) was synthesized and its photochemical properties were characterized by measuring UV-VIS,cyclic voltammograms and fluorescence spectra.The SnTPPSNA₄ was applied to a new type of photoinduced oxygen evolution system as a photosensitive oxidant and the best experimental conditions for this research are discussed in this paper.From the results,it is clear that,under the present condition,SnTPPSNA₄ could efficiently oxide water to evolve oxygen when compared to the conventional oxidant-ruthenium complex([Ru(bpy)₃]²⁺).
