Ultraviolet radiation splitting water

Ultraviolet light and Ionizing radiation homolytically split water to form the hydroxyl radical and hydrogen. [Pg.34]

Much of solar radiation lies in the infrared part of the spectrum and is of too low energy to be utilized in conventional PV cells (or in photo-electrochemical reactions see below) so that it is wasted. To harness this thermal energy and thereby improve the efficiency of solar energy conversion, Licht has proposed the use of dielectric filters to separate the radiation received by the solar tower into an infrared component to heat pressurized water to at least 300 °C and an optical/ultraviolet component to generate electricity through PV (or photo-electrochemical) cells. The electricity would then be used to split water by high-temperature steam electrolysis (see above) with the entropy term Th.S of Figure... [Pg.124]
