Exceptionally fast electrocatalytic H2 production (up to 3 x 107 s -1) at overpotentials of ~400 mV are catalysed by [Ni(PPh2NC6H4X2)2]2+ complexes in an acidic ionic liquid - water medium ([(DMF)H]NTf2-H2O, ?H2O = 0.71). This research was supported as part of the Center for Molecular Electrocatalysis, an Energy Frontier Research Center funded by the US Department of Energy, Office of Science, Office of Basic Energy Sciences and the Office of Science Early Career Research Program through the US DOE, BES (W.J.S.). Pacific Northwest National Laboratory is operated by Battelle for the US Department of Energy.
