  • Patent number: 11358113
    Abstract: Embodiments relate to generating non-thermal plasma to selectively convert a precursor to a product. More specifically, plasma forming material, a precursor material, and a plasma promoter material are provided to a reaction zone of a vessel. The reaction zone is exposed to microwave radiation, including exposing the plasma forming material, the precursor material, and the plasma promoter material to the microwave radiation. The exposure of the plasma forming material and the plasma promoter material to the microwave radiation selectively converts the plasma forming material to a micro-plasma. The precursor material is mixed with the plasma forming material and the precursor material is exposed to the micro-plasma. The exposure of the precursor material to the micro-plasma and the microwave radiation selectively converts the precursor material to a product.

  • Patent number: 11342131
    Abstract: Disclosed is a semiconductor-liquid junction based photoelectrochemical (PEC) cell for the unassisted solar splitting of water into hydrogen and oxygen gas, the solar-driven reduction of CO2 to higher-order hydrocarbons, and the solar-driven synthesis of NH3. The disclosed system can employ a photocathode based upon wurtzite hexagonal semiconductors that can be tailored with proper band alignment for the redox potentials for water, CO2 reduction, and NH3 production, and with bandgap energy for maximum solar absorption. The design maximizes the carrier collection efficiency by leveraging spontaneous and piezoelectric polarization in these materials systems to generate hot electrons within the photocathode. These electrons have sufficient excess energy, preserved at a designed energy capture region, to overcome the kinetic overpotential (surface chemistry limitation) required for the reactions to occur at a high rate.

  • Patent number: 11291972
    Abstract: A method of dissociating hydrogen and oxygen from a water molecule comprises isolating a predetermined volume of water between concentrically-mounted electrodes; applying a magnetic field across the predetermined volume of water, the magnetic field focused radially and attracting diametrically across the electrodes; exciting water molecules in the isolated volume of water to a resonant harmonic frequency; and synchronously applying short burst high voltage, high frequency AC pulse packets to the isolated volume of water to create an electric field. The AC pulse packets have a burst width of up to 1 millisecond and a voltage up to about 10 MV, and generate an oscillating electromotive force which acts on the excited water molecules to dissociate hydrogen and oxygen.

  • Patent number: 10899611
    Abstract: The process describes the capability of solid-state metals to oxidize in water to produce hydrogen when stimulated by laser. The solid-state metals with an adherent surface layer of the oxide component is introduced into water or another suitable oxidizer. The metal-oxidizer reaction to form hydrogen is initiated and maintained by a laser periodically/continually ablating the metal. The energy, pulse duration and wavelength of the laser may be tailored to control the rate of reaction of the source material with the oxidizer, and thereby control the rate of formation of hydrogen. Application of energy produced by such method may include powering large scale commercial and residential energy companies, providing sustainable and continuous fuel for intergalactic missions, providing an alternative fuel sources for on-board hydrogen-powered vehicles and smaller scale applications such as emergency generators.
