  • Catalyst for hydrogen generation from small organic molecules
    Patent number: 8754000
    Abstract: A catalyst for the generation of hydrogen from a small organic molecule comprises a tertiary metal composition where: the first metal is either Pt or Ru; the second metal is at least one of Pt, Ru, Au, Pd, Rh, Ir, Os, and/or Re; and Bi, primarily present in the form of an oxide or of a mixture of oxides and carbonates and in the +3 oxidation state. A portion of the first and/or second metal may be in the form of an oxide. The catalyst can be in the form of a nanoparticle and supported on an inert substrate, such as carbon. The catalyst can be used for dehydrogenation of formic acid or other small organic molecules in a liquid state at ambient pressures and at temperatures below the boiling point of the liquid. The liquid can be an aqueous solution of the small organic molecule.
