... – 1100 ° C to form Fe 3 + -YSZ that is reactivated by thermal reduction in a separate step at temperatures above 1400 ° C under an inert atmosphere. In the present study, ceramic foam coated with Fe-YSZ particles is examined as the thermochemical water-splitting device to be used in a solar directly...

... kW m − 2 ). The new type of catalytically activated ceramic foam absorber—a Ru ∕ Ni - Mg - O catalyzed SiC-foam absorber—was prepared, and its activity was tested in a laboratory-scale volumetric receiver-reactor with a transparent (quartz) window by using a sun-simulator. Compared to conventional Rh...
