| Outline of Final Research Achievements |
Brownmillerite-type Ca2Fe2CoO5 showed excellent catalytic activity for oxygen evolution reaction. The Ca2Fe2-xCoxO5 ultrafine particles with nano-metric dimension can be synthesized by reverse micelle method on TiO2 nanoparticles. The ratio of cobalt to iron contained in the particles was easily controlled by changing the mixing ratio of starting materials. The precursors of Ca2Fe2CoO5 must be calcined after loading on TiO2 nanoparticles to get ultrafine particles with several nanometers in size. The amount of oxygen at 1 wt% Ca2FeCoO5/TiO2 for photocatalytic water splitting using silver fluoride was 1.5 times as large as that at TiO2.
