Joint international project of Niigata University (Japan) -Korean Institute of Energy Research, KIER (Kora) on the "Solar demonstration of Water-Splitting Reactor using Ceramic Foam Device" aims to develop a novel-type of solar reactor with reactive cerium- or iron oxides-coated foam devices for high-temperature two-step thermochemical water splitting cycle, and to demonstrate its performances on sun with a 40-kW_<th> solar furnace. The reactive CeO_2 foam device for the two-step water splitting is proposed and prepared by Niigata University, Japan, and involves coating an inert zirconia foam with reactive CeO_2 or ferrite-zirconia redox materials. The project includes the development of reactive foam devices, the new design and the fabrication of solar reactor with the reactive foam devices, and finally the solar demonstration on the KIER's 45-kW_<th> solar furnace in Korea. In this paper, highly-active CeO_2 particles were used as a redox material for preparing CeO_2 foam devices. A ceramic foam disk made of MgO partially-stabilized Zirconia (MPSZ) was used as a ceramic matrix that was coated with the CeO_2 particles. Solar thermochemical two-step water splitting was demonstrated using the prepared CeO_2-coated MPSZ (CeO_2/MPSZ) foam devices in Korea.
