  • Patent number: 10549236
    Abstract: Systems and methods use oxygen uncoupling metal oxide material for decomposition of NOx. A gaseous input stream comprising NOx is contacted with a metal oxide particle, generating nitrogen (N2) gas and an oxidized metal oxide particle. After contacting the first gaseous input stream with the metal oxide particle, a first gaseous product stream is collected. The first gaseous product stream includes substantially no NOx. A second gaseous input stream comprising at least one sweeping gas is also contacted with the oxidized metal oxide particle. After contacting the oxidized metal oxide particle, the sweeping gas includes oxygen (O2) and a reduced metal oxide particle is generated. Then a second gaseous product stream is collected, where the second gaseous product stream includes oxygen (O2) gas.
