Abstract
The thermochemical two-step water splitting was examined on ZrO 2 -supported Co(II)-ferrites below 1400 °C, for purpose of converting solar high-temperature heat to clean hydrogen energy as storage and transport of solar energy. The ferrite on the ZrO 2 -support was thermally decomposed to the reduced phase of wustite at 1400 °C under an inert atmosphere. The reduced phase was reoxidized with steam on the ZrO 2 -support to generate hydrogen below 1000 °C in a separate step. The ZrO 2 -supporting alleviated the high-temperature sintering of iron oxide. As the results, the ZrO 2 -supported ferrite realized a greater reactivity and a better repeatability of the cyclic water splitting than the conventional unsupported ferrites. The Co x Fe 3− x O 4 /ZrO 2 with the x value of around 0.4–0.7 was found to be the promising working material for the two-step water splitting when thermally reduced at 1400 °C under an inert atmosphere.
