A solar concentrator reactor system and method of use for high temperature thermochemical processes. In one embodiment, the solar concentrator reactor system produces a thermochemical reaction of irradiated particles within an enclosed vessel volume of a solar concentrator reactor. In one aspect, the solar concentrator reactor system uses a solar concentrator to irradiate particles of a particle stream within an enclosed vessel volume of a solar concentrator reactor. The thermochemical reaction yields a chemical change of the feedstock and/or phase transition of the feedstock such as the production of a molten reacted material from a solid particulate feed. In one embodiment, the particles are a lunar regolith and the thermochemical reaction yields oxygen.

The present application discloses a method for preparing deuterium depleted water, wherein natural water is fed into the device of the present disclosure, and the liquid phase stream continuously flows backwards stage by stage under the combined action of the low-pressure steam compressors and the stream delivery pumps. In a single-stage system, the deuterium is deprived depending on the difference in vapor pressure between .sup.1H.sub.2O and .sup.2H.sub.2O (and/or .sup.1H.sup.2HO), and finally, the deuterium depleted water is produced.

The present disclosure provides a method for preparing hydronium ion-dissolved water including: (a) purifying distilled water to prepare deionized water; (b) electrolyzing the water to produce a brown gas stream; (c) mixing air with the brown gas stream to form a mixed gas stream; (d) injecting the mixed gas stream into the deionized water and dissolving the mixed gas to prepare gas-dissolved water; and (e) injecting the gas-dissolved water into thin-layer chromatography, filtering the gas-dissolved water through a stationary phase provided inside the thin-layer chromatography, and then fractionating to adjust the concentration of dissolved gas. Accordingly, functional water in which hydronium ions are dissolved can be effectively prepared.

Embodiments of the present disclosure are directed to hydrogen-selective oxygen carrier materials and methods of using hydrogen-selective oxygen carrier materials. The hydrogen-selective oxygen carrier material may comprise a core material, which includes a redox-active transition metal oxide; a shell material, which includes one or more alkali transition metal oxides; and a support material. The shell material may be in direct contact with at least a majority of an outer surface of the core material. At least a portion of the core material may be in direct contact with the support material. The hydrogen-selective oxygen carrier material may be selective to combust hydrogen in an environment that includes hydrogen and hydrocarbons.

The present disclosure provide for methods of reforming a hydrocarbon such as methane. In an aspect, when the method is driven via renewable energy (e.g., use of solar energy, wind energy, or other renewable energy) and coupled with zero-energy input product gas separation, this enables the capture of pure CO.sub.2 (i.e., carbon sequestration) and carbon-neutral utilization of methane can be achieved. As a result, the present disclosure can provide for a method to reform methane with zero-energy input product gas separation.
