Abstract

Catalysts that efficiently interconvert between electrical energy and chemical bonds (fuels) are needed for a sustainable and flexible energy supply. Reactions that involve transfer of multiple protons and electrons are pervasive in energy science, as exemplified by the two-proton, two-electron oxidation of H2 and the reverse, production of H2 by reduction of protons. Pendant amines incorporated into diphosphines function as proton relays, lowering the barrier for proton mobility and assisting in formation and cleavage of the H-H bond. A series of Ni(II) and Co(II) complexes with diphosphine/pendant amine ligands catalyze the production of H2, and related Ni(II) catalysts catalyze the oxidation of H2. Mn and Fe complexes with diphosphine/pendant amine ligands are also capable of heterolytic cleavage of H2 under some conditions.
