An important prerequisite for the widespread use of energy from renewable sources is the ability to store and recover the energy on demand. The high energy density of chemical bonds makes chemical fuels, such as hydrogen, ideal for energy storage. To this end, efficient and economical catalysts are required for fuel production and oxidation. Hydrogen oxidation and production are multi-electron and multi-proton transformations. The incorporation of proton relays in the secondary coordination sphere of nickel diphosphine complexes is essential to enhancing catalytic rates and improving catalyst efficiency. Mechanistic and theoretical studies on the function of the relays and their role in the catalytic cycles will be presented.
