Abstract

Increased use of carbon-neutral energy sources requires large scale, reliable storage of energy, due to the intermittent nature of solar and wind energy. Catalysts that efficiently interconvert between electrical energy and chemical bonds (fuels) are needed for a sustainable and flexible energy supply that involves minimal production of greenhouse gases. Reactions that involve transfer of multiple protons and electrons are pervasive in energy science, as exemplified by the two-proton, two-electron oxidation of H 2 and the reverse, production of H 2 by reduction of protons. A series of Ni(diphosphine) 2 2+complexes are catalysts for H 2 production, some with turnover frequencies greater than 1000 s -1. Related Ni(diphosphine) 2 2+ complexes are electrocatalysts for oxidation of hydrogen. Pendant amines incorporated into diphosphines function as proton relays, lowering the barrier for proton mobility and assisting in formation or cleavage of the H-H bond.
