Patent number: 9566574Abstract: Catalysts that include at least one catalytically active element and one helper catalyst can be used to increase the rate or lower the overpotential of chemical reactions. The helper catalyst can simultaneously act as a director molecule, suppressing undesired reactions and thus increasing selectivity toward the desired reaction. These catalysts can be useful for a variety of chemical reactions including, in particular, the electrochemical conversion of CO2 or formic acid. The catalysts can also suppress H2 evolution, permitting electrochemical cell operation at potentials below RHE. Chemical processes and devices using the catalysts are also disclosed, including processes to produce CO, OH?, HCO?, H2CO, (HCO2)?, H2CO2, CH3OH, CH4, C2H4, CH3CH2OH, CH3COO?, CH3COOH, C2H6, O2, H2, (COOH)2, or (COO?)2, and a specific device, namely, a CO2 sensor.Type: GrantFiled: June 30, 2011Date of Patent: February 14, 2017Assignee: Dioxide Materials, Inc.Inventors: Richard I.

Patent number: 9193593Abstract: An environmentally beneficial process for the production of fuels and chemicals employs carbon dioxide from a natural source or from an artificial chemical source that would otherwise be discharged into the environment. The carbon dioxide is converted to formic acid and the formic acid is then non-biologically converted to fuels and/or chemicals without the intermediate process of hydrogenating the formic acid to methanol or reacting the formic acid with ammonia to form formamide. In the present process, formic acid is converted to one of seven primary feedstocks: formaldehyde, acrylic acid, methane, ethylene, propylene, syngas, and C5-C7 carbohydrates. The formaldehyde, acrylic acid, methane, ethylene, propylene, syngas and/or short chain carbohydrates can either be used directly, or can be converted into a wealth of other products.Type: GrantFiled: February 24, 2013Date of Patent: November 24, 2015Assignee: Dioxide Materials, Inc.Inventors: Richard I.
