The present report summarizes work on the metal oxide photoanodes conducted under the present contract. The objective of the program was to develop practical photoelectrodes for use in the photoelectrolysis of water. Evidence is provided for an operative TiO/sub 2//Fe/sub 2/O/sub 3/ heterojunction anode. As yet unexplained instabilities were observed with TiO/sub 2/ anodes when operated in excess of 100 hs. Studies on polycrystalline In/sub 2/O/sub 3/ indicated photoefficiencies comparable to that of single crystal material. Efforts to improve the efficiency of polycrystalline In/sub 2/O/sub 3/ by the addition of Y/sub 2/O/sub 3/ were unsuccessful. Studies were also conducted on solid state electrochemical techniques for doping TiO/sub 2/ with fluoride. A 30% increase in efficiency was noted at relatively low levels but a decrease was observed at higher doping levels.
