  • Materials for ammonia synthesis
    Patent number: 12012662
    Abstract: Disclosed herein are doped perovskite oxides. The doped perovskite oxides may be used as a cathode material in an electrochemical cell to electrochemically generate ammonia from N2. The doped perovskite oxides may be combined with nitride compounds, for instance iron nitride, to further increase the efficiency of the ammonia production.
    Type: Grant

  • HETEROATOM-DOPED CARBON CATALYST FOR ELECTROCATALYTIC HALOGEN PRODUCTION
    Publication number: 20190338427
    Abstract: Disclosed herein are methods of electrochemically producing halogen using an oxygen consuming gas diffusion electrode, referred to herein as an oxygen depolarized cathode (ODC). The electrode can include heteroatom-doped carbon nanostructures as catalysts for both halogen evolving anodes and oxygen depolarized cathodes. Examples of halogens that can be produced include chlorine and bromine by oxidation of the respective halide ions.

  • Multi-stage catalyst systems and uses thereof
    Publication number: 20070110651
    Abstract: Catalyst systems and methods provide benefits in reducing the content of nitrogen oxides in a gaseous stream containing nitric oxide (NO), hydrocarbons, carbon monoxide (CO), and oxygen (O2). The catalyst system comprises an oxidation catalyst comprising a first metal supported on a first inorganic oxide for catalyzing the oxidation of NO to nitrogen dioxide (NO2), and a reduction catalyst comprising a second metal supported on a second inorganic oxide for catalyzing the reduction of NO2 to nitrogen (N2).

  • Novel catalyst systems and uses thereof
    Publication number: 20060257304
    Abstract: A method of carbon monoxide (CO) removal comprises providing an oxidation catalyst comprising cobalt supported on an inorganic oxide. The method further comprises feeding a gaseous stream comprising CO, and oxygen (O2) to the catalyst system, and removing CO from the gaseous stream by oxidizing the CO to carbon dioxide (CO2) in the presence of the oxidation catalyst at a temperature between about 20 to about 200° C.
