Solar thermochemical splitting of h2o and Co2 using nonvolatile metal oxides

In this study, a Co ferrite/ZrO2 ceramic nanornixture was synthesized by the propylene-oxide-assisted sol-gel method. Cobalt, iron, and zirconium nitrate salts were used as the metal precursors, and ethanol and propylene oxide were used as the solvent and gelation agent, respectively. The prepared gels were aged, dried, and annealed at 1000°C for different dwell times. The annealed Co ferrite/ZrO2 powder was analyzed by powder X-ray diffraction (PXRD), Brunauer-Emmett-Teller surface area analysis (BET), and energy-dispersive spectroscopy (EDS). The characterization results are reported in detail.This publication was made possible by the NPRP grant (NPRP8-370-2-154) from the Qatar National Research Fund (a member of Qatar Foundation).
