  • Mixed metal oxide extrudate catalyst
    Patent number: 10618042
    Abstract: Methods of making a Ce0.6Zr0.4O2 supported NiMg catalyst extrudate are provided. In some aspects, the methods include preparing a ceria-zirconia solution comprising Ce(NO3)3.6H2O, ZrO(NO3)2xH2O, and water; forming a precipitate; drying and calcining the precipitate to produce a Ce0.6Zr0.4O2; adding a nickel-magnesium solution to the Ce0.6Zr0.4O2 to produce the NiMg/Ce0.6Zr0.4O2; and drying and calcining a wet extrudate of the NiMg/Ce0.6Zr0.4O2 to produce the Ce0.6Zr0.4O2 supported NiMg catalyst extrudate. Ce0.6Zr0.4O2 supported NiMg catalyst extrudates made by the methods are also provided.

  • Systems and methods for converting carbon dioxide into chemical feedstock
    Patent number: 9815702
    Abstract: Provided herein are systems containing a solar reactor having a mixture of plasmonic material and oxygen-conducting material that can convert carbon dioxide into a chemical feedstock.
    Type: Grant
    Filed: March 6, 2015
    Date of Patent: November 14, 2017

  • Systems and methods for converting carbon dioxide into chemical feedstock
    Patent number: 8999283
    Abstract: In one embodiment, carbon dioxide is converted into a chemical feedstock by providing a mixture of plasmonic material and oxygen-conducting material, exposing the mixture to sunlight so that solar energy is absorbed by the plasmonic material which then heats the oxygen-conducting material so that oxygen vacancies are generated, passing carbon dioxide through the mixture, and the oxygen-conducting material removing oxygen atoms from the carbon dioxide to form carbon monoxide.
