| Outline of Final Research Achievements |
This project aims at the development of water splitting device with a “thermal-photo-hybridized” activity via solar demonstration, in order to reduce the reaction temperature of solar two-step water splitting cycle with a redox metal oxide. It is well known that cerium oxide (ceria) has a high thermal activity as a working reactive ceramic (redox metal oxide) for solar “thermochemical” two-step water splitting cycle. In this project, iron oxide, which has “photochemical activity”, was doped into ceria, and then, small ceramic foams were coated with the iron-doped ceria powder. The prepared reactive foam devices were tested on activity for the two-step water splitting cycle under irradiation of artificial solar fluxes from a sun-simulator. Under the experiments, the new devices were found to split water at temperatures below 1300C while the conventional device without doping of iron-oxide needs temperatures above 1500C.
