Gan, Lu Groy, Thomas L. Tarakeshwar, Pilarisetty K. S. Mazinani, Shobeir Shearer, Jason Mujica, Vladimiro Jones, Anne K. A Nickel Phosphine Complex as a Fast and Efficient Hydrogen Production Catalyst Here we report the electrocatalytic reduction of protons to hydrogen by a novel S<sub>2</sub>P<sub>2</sub> coordinated nickel complex, [Ni­(bdt)­(dppf)] (bdt = 1,2-benzene­dithiolate, dppf = 1,1′-bis­(diphenyl­phos­phino)­ferro­cene). The catalysis is fast and efficient with a turnover frequency of 1240 s<sup>–1</sup> and an overpotential of only 265 mV for half activity at low acid concentrations. Furthermore, catalysis is possible using a weak acid, and the complex is stable for at least 4 h in acidic solution. Calculations of the system carried out at the density functional level of theory (DFT) are consistent with a mechanism for catalysis in which both protonations take place at the nickel center. acidic solution;electrocatalytic reduction;265 mV;novel S 2P;catalysi;Nickel Phosphine Complex;half activity;turnover frequency;DFT;4 h;nickel center;acid concentrations;Efficient Hydrogen Production CatalystHere 2015-01-28
