  • Patent number: 11964230
    Abstract: A system configured to capture CO2 and able to be washed of the captured CO2 includes a material including an ionic liquid configured to capture CO2 in response to exposure to a gas comprising CO2 and to a thermal energy source and an aerogel holding the ionic liquid therein. The system may also include a washing solution configured to wash the captured CO2 from the material.
    Type: Grant
    Filed: October 6, 2022
    Date of Patent: April 23, 2024
    Assignee: University of Houston System
    Inventors: Hadi Ghasemi, Varun Kashyap, T. Randall Lee, Riddhiman Medhi

  • Patent number: 11541349
    Abstract: A method of capturing CO2 and converting the captured CO2 into useful byproducts includes providing a material including a material matrix holding an ionic liquid, exposing the material to a source of thermal energy to capture CO2 within the material, removing the material from exposure to the source of thermal energy, and washing the material with a solution to convert the captured CO2 and wash the converted, captured CO2 from the material as filtrate. Materials and systems for capturing CO2 and converting the captured CO2 into useful byproducts are also provided.

  • Publication number: 20220169525
    Abstract: The present disclosure relates to a strategy to synthesize antimony- and zinc-doped tin oxide particles with tunable band gap characteristics. The methods yield stable and monodispersed particles with great control on uniformity of shape and size. The methods produce undoped and antimony and zinc-doped tin oxide stand-alone and core-shell particles, both nanoparticles and microparticles, as well as antimony and zinc-doped tin oxide shells for coating particles, including plasmonic core particles.
