PROMISSING CERIUM-DOPED BARIUM MANGANATE PEROVSKITE FOR SOLAR THERMOCHEMICAL HYDROGEN PRODUCTION

摘要

Over the past decade, nonstoichiometric oxides have been investigated for solar thermochemical water splitting applications because of their ability to partially reduce and create oxygen vacancies at high temperatures and subsequently reoxidize in steam at lower temperatures, uptaking the oxygen into the lattice and producing hydrogen as a consequence (c.f. Figure 1a).
