In this work, we investigate YMnO3 perovskites with Sr2+ and Al3+ doping, Y1–xSrxMn1–yAlyO3, for use in thermochemical H2O or CO2 splitting for the first time. Oxygen nonstoichiometries (δ) with x ...

A novel chemical-looping combustion scheme is proposed, where facile gas separation via steam condensation enables the production of sequestrable CO2 from alkanes, such as CH4, and pure H2 from H2O. This cycle consists of two steps, namely, (1) the e

Thermodynamic data for several LaMnO3-based perovskites indicates that in the high oxygen partial pressure (pO2) range (e.g., 10–7 to 10–3 atm), where isothermal thermochemical redox cycling is via...

Electrodynamic dust shield (EDS) uses traveling-wave or standing-wave electrodynamic effects to repel dust particles from a surface, and has been proposed as a potential anti-dust solution for mitigating soiling loss in solar energy applications. In

A kinetic relaxation study of the partial oxidation of methane over ceria in the absence of gas-phase oxygen, a promising pathway for syngas production, was performed under atmospheric pressure between 750 °C and 1100 °C. Using a thermogravimetric

Solar thermochemical (STC) redox cycles have made substantial advances in recent years, in large part due to the utilization of nonstoichiometric ceria over other iron oxide and zinc oxide based materials that undergo crystallographic or solid-to-gas
