  • Bimetallic catalysts for COhydrogenation and Hgeneration from formic acid and/or salts thereof
    Patent number: 9095846
    Abstract: The invention relates to a ligand that may be used to create a catalyst including a coordination complex is formed by the addition of two metals; Cp, Cp* or an unsubstituted or substituted ?-arene; and two coordinating solvent species or solvent molecules. The bimetallic catalyst may be used in the hydrogenation of CO2 to form formic acid and/or salts thereof, and in the dehydrogenation of formic acid and/or salts thereof to form H2 and CO2.
    Type: Grant
