Research output: Contribution to journalConference article


A series of nickel(II) bis(diphosphine) complexes that incorporate amine bases in the second coordination sphere have been synthesized and found to serve as electrocatalysts for the formation or oxidation of hydrogen. The role of the pendant amines in promoting the catalytic activity has been studied, and aspects of ligand design have been probed in order to enhance catalytic rates. Variations in phosphine and amine substituents, as well as structural ligand modifications that vary the number and positioning of the bases have led to highly efficient electrocatalysts with rates that, in some cases, equal or surpass those of the nickel/iron hydrogenase enzymes.
