The goal of the program is to demonstrate that an inexpensive heterogeneous photocatalyst may efficiently decompose water to hydrogen and oxygen (or H/sub 2/O/sub 2/) with sunlight. The research is specifically focused on sensitization of known photocatalysts to the sunlight spectrum. The authors demonstrated short circuit photocurrent response in the visible with chromium-doped TiO/sub 2/ in an electrochemical cell. It was also shown that in an inexpensive manner TiO/sub 2/ could be easily grown electrochemically. Cu/sub 2/O was grown by oxidation of copper. Sputtering of Cu/sub 2/O to make a Cu/sub 2/O/TiO/sub 2/ heterojunction is being investigated.
