Like a differential gear: Upon irradiation with visible light, excited dye molecules inject electrons into TiO2 and form dye radicals, which can oxidize TEMPO to TEMPO+, which in turn oxidizes alcohols in the presence of O2 selectively to corresponding aldehydes. One reason for the selectivity is that the irradiation is downshifted to visible light.
