Title: Electrocatalytic H 2 production with a turnover frequency >10 7 s -1: the medium provides an increase in rate but not overpotential

In this paper, rapid proton movement results in exceptionally fast electrocatalytic H 2 production (up to 3 × 10 7 s -1) at overpotentials of ~400 mV when catalysed by [Ni(P Ph 2N C6H4x 2) 2] 2+ complexes in an acidic ionic liquid–water medium ([(DMF)H]NTf 2–H 2O, χ H2O = 0.71).
