Photosensitized decomposition of hydrogen peroxide by the uranyl ion, production of hydroperoxide radicals
Description
The photosensitized decomposition of hydrogen peroxide by the uranyl ion in sulfuric acid media has been demonstrated and the kinetics of oxygen evolution have been measured as a function of the initial concentrations. The HO2 radical stabilized by complexation with UO22+ is an intermediate in this decomposition. This reaction can be employed in the photoassisted oxidation of diverse organic molecules using UO22+ as the sensitizer
