We have developed reactive foam devices in Niigata University for solar thermochemical two-step water-splitting to produce hydrogen from water. The hydrogen productivity of the reactive foam devices was cyclically examined as an international collaboration research by using 45kW_<th> dish type solar concentrator in Korea Institute of Energy Research at Korea. Different shape of foam devices and radiation method of solar furnace were tested for solar demonstration.

4-2-2 High Activation of Redox Material Based on Metal Oxide for Thermochemical Two-Step Water-Splitting cycle

SUDA Toshinori, HATAMACHI Tsuyoshi, GOKON Nobuyuki, KODAMA Tatsuya

Proceedings of the Annual Conference of The Japan Institute of Energy 24 174 - 175 2015

Language：Japanese Publisher：The Japan Institute of Energy

Cerium oxide was examined as a redox material on cyclic reactivity for converting high-temperature heat into chemical fuels via solar two-step thermochemical water-splitting. In this study, in order to increase hydrogen and oxygen production in comparison to pure CeO_2, we synthesized a doping of 30mol% metal ion to the CeO_2 (30mol%M-CeO_<2-δ>), and tested the 30mol%M-CeO_<2-δ> powder for thermochemical two-step water-splitting to produce hydrogen and oxygen during cyclic reaction. The reactivity of the M-CeO_<2-δ> powder was evaluated for several cycles.
