  • High-efficiency oxygen reduction to hydrogen peroxide catalyzed by oxidized carbon materials
    Patent number: 11168403
    Abstract: Improved electrochemical production of hydrogen peroxide is provided with a surface-oxidized carbon catalyst. The carbon can be, for example, carbon black or carbon nanotubes. The oxidation of the carbon can be performed, for example, by heating the carbon in nitric acid, or by heating the carbon in a base. The resulting carbon catalyst can have a distinctive oxygen is peak in its X-ray photoelectron spectrum.
    Type: Grant
    Filed: December 14, 2018
    Date of Patent: November 9, 2021
    Assignee: The Board of Trustees of the Leland Stanford Junior University
    Inventors: Yi Cui, Zhiyi Lu, Guangxu Chen
  • N- and O-Doped Carbon with High Selectivity for Electrochemical H2O2 Production in Neutral Condition
    Publication number: 20200173045
    Abstract: Improved electrochemical production of hydrogen peroxide is provided with a mesoporous carbon catalyst is both O- and N-doped. The resulting catalyst works pH-neutral solutions to enable applications such as environmental water treatment.
