Summary: Characterization of promising non-stoichiometric-perovskite-type
oxide catalysts for solar thermochemical fuel productions
Description: Solar thermochemical (STC) fuel productions is a process that utilizes
concentrated solar radiation to thermochemically split water molecules to
hydrogen and oxygen. While this process has high theoretically efficiencies,
current STC methods fall significantly short of this potential and are primarily
limited by the lack of adequate redox materials. This invention relates to a STC
method that utilizes non-stoichiometric-perovskite-type oxides. A framework was
developed for implementing the rapid screening and characterization of
promising oxide candidates by x-ray diffraction and a novel thermogravimetric
STC redox cycle screening experiment. Several perovskites with thermodynamic
redox properties are potentially highly active catalyst for solar-thermal splitting of
water as well as carbon dioxide decomposition and synthesis gas production.
Main Advantages of this Invention:
 High-efficiencies
Potential Areas of Application:
 Biofuel production
