Generation of hydrogen from photocatalytic cleavage of water
- Univ. of Oklahoma, Norman, OK (United States)
This paper describes the objectives, methods and early results on the US Department of Energy sponsored project to generate hydrogen from splitting of water using photocatalysts. The approach uses organometallic photosensitizers adsorbed onto platinated titania. Platinized titania is a photocatalyst for water splitting, but does not absorb sunlight in the visible range, where most of the sun`s energy is contained. Organometallic photosensitizers are synthesized, attached to platinized titania and characterized by UV-Vis spectroscopy, cyclic voltammetry, action spectra and hydrogen generation ability. Thus far, Copper, Iron and Ruthenium catalyst systems have been produced and characterized in this manner. Suitable sensitized systems that have the desirable properties have not yet been found.
