  • Non-noble metal electrocatalysts for oxygen depolarized cathodes and their application in chlor-alkali electrolysis cells
    Patent number: 10854885
    Abstract: A simplified and efficient method for preparing non-noble metal catalysts for oxygen reduction reaction (ORR) based on nitrogen containing metal organic framework (MOF) is provided. The method includes formation of a first MOF product through a mechano-chemical reaction between a first transition metal compound and a first organic ligand in the presence of a catalyst. It further includes formation of a second MOF product incorporating a second transition metal and a second organic ligand into the first-MOF product. The second MOF product is converted into an electrocatalyst via pyrolysis, and optionally post-treatment. The electrocatalysts are applicable in various electrochemical systems, including oxygen depolarized cathodes (ODC) for chlorine evolution.

  • Isolation and confirmation of analytes from test devices
    Patent number: 7241626
    Abstract: Methods, articles, and kits for obtaining elevated concentrations of a substance from a sample that has become bound, for example by providing a positive test result in an immunoassay or other binding assay. The concentrated substance is optionally subjected to further processing or analysis, for example to confirm the identity of the substance, such as a pathogenic organism in a food sample.
