Abstract
Eosin Y was not photobleached with triethanolamine (TEOA) on visible light irradiation in the presence of methyl viologen (Mv2+), and worked as an effective sensitizer to reduce Mv2+ into MV+· with TEOA in aqueous ethanol. The resulting MV+· reduced water to hydrogen in the presence of colloidal platinum in the same solvent. The quantum yield for MV+· formation was measured to be ca. 0.3.Keywords
