Title: Metal Photochemistry

Abstract: Some metals undergo photochemical oxidation reactions and produce dihydrogen upon ultraviolet irradiation in aqueous acidic solutions. Research has been done on metals such as Chromium, Copper, Cerium, Iron, Europium, and Manganese. Photochemical oxidation reactions involving these metals induced with an ultraviolet lamp cause an increase in charge to the metal ions. Explanations for the reactions and experimental procedures will be discussed as well as data obtained such as quantum yields for production of dihydrogen. Various mechanisms that have been suggested will be reviewed.
