Abstract: A method and reactor for a hybrid thermo-electrochemical cycle using a layered reactive element is disclosed. The method includes heating the reactive element with a heat source, the reactive element having a metal oxide core that is redox-active, an outer layer, and an ion conductor layer between the core and the outer layer. The method includes increasing a chemical potential of oxygen in the core, driving O2− ions out as O2, the chemical potential increased through applying a first bias voltage between the core and the outer layer. The method includes exposing the reactive element to an input gas, and decreasing the chemical potential of oxygen in the core, driving oxygen from the input gas into the core leaving a gas product, the chemical potential decreased through applying a second bias voltage between the core and the outer layer. The first and second bias voltages have opposite polarity.

Abstract: A rapid method of synthesizing nanoflowers made of nanoflakes of nickel molybdate (NiMoO4) directly on nickel foam (NF) through an aerosol-assisted chemical vapor deposition (AACVD) process is disclosed. The nickel molybdate nanoflowers were grown on NF by varying the deposition time for 60 and 120 min at a fixed temperature of 480° C. and their efficiency was investigated as oxygen evolution reaction (OER) catalysts in 1 M KOH electrolyte. The NiMoO4 nanoflowers of NF obtained after 60 minutes of AACVD process showed OER performance with lowest overpotential of 320 mV to reach standard current density of 10 mA cm−2. The catalyst continuously performed the OER for 15 h, signifying its prominent stability under electrochemical conditions.

Abstract: A method of forming a hydrocarbon product and hydrogen gas comprises introducing CH4 to a positive electrode of an electrochemical cell comprising the positive electrode, a negative electrode, and a proton-conducting membrane between the positive electrode and the negative electrode. The proton-conducting membrane comprises an electrolyte material having an ionic conductivity greater than or equal to about 10−2 S/cm at one or more temperatures within a range of from about 150° C. to about 600° C. A potential difference is applied between the positive electrode and the negative electrode of the electrochemical cell to produce the hydrocarbon product and the hydrogen gas. A CH4 activation system and an electrochemical cell are also described.
