OSTI ID:5062751
In our study of intermediates from excited-state electron-transfer reactions, we have focused our attention during the past year on MV/sup +/., the reduced methyl viologen radical cation, which is a precursor to the formation of H/sub 2/ in the photosensitized reduction of water. Through the use of photochemical and radiation chemical techniques, we have examined the efficiency of interaction of MV/sup +/. with colloidal Pt, the stability of MV/sup +/. as a function of pH, the quantum yield of formation of MV/sup +/. in the Ru(bpy)/sub 3//sup 2 +//MV/sup 2 +//EDTA system, and the formation of photoactive charge-transfer complexes between MV/sup 2 +/ and sacrificial electron donors.
