Iron precipitated onto ceria-zirconia nanoparticle mixtures for the production of hydrogen via two-step thermochemical water splitting

Recent Developments in Ceria-Driven Solar Thermochemical Water and Carbon Dioxide Splitting Redox Cycle

“…Roberts et al [61] explored the influence of adding ceria to the iron oxide/zirconia solid solution on thermochemical WS application. At a constant TR temperature = 1450 • C, adding ceria to the iron oxide/zirconia solid solution significantly improved H 2 production at a WS temperature of 1200 • C. In contrast, there was no enhancement in the H 2 production at a WS temperature equal to 1000 • C. Dähler et al [62] designed and fabricated a solar dish concentrating system for solar thermochemical fuel production (Figure 9).…”

K-doped CeO2–ZrO2 for CO2 thermochemical catalytic splitting

“…Two-step thermochemical cycles can be carried out under either isothermal [31][32][33][34][35][36] or temperature-swing conditions. 1,12,[37][38][39][40] The best operating conditions depend on several parameters and their individuation is not an easy feat. [41][42][43][44][45] In this work, we simulated the possibility of the catalyst to undergo isothermal reduction/oxidation cycles by switching the CO 2 concentration without changing the operating temperature in order to compare isothermal and temperature-swing conditions.…”
