a Photograph of Mo2N catalyst on Nafion 115 membrane. Catalyst loading: 1.0 mg cm−2. b Current-voltage polarizations of the zero-gap membrane flow electrolyser using Mo, Mo2N, and commercial Pt/C as the cathodic catalysts. c, Chronopotentiometry measurement of the electrolyser at 1 A cm−2 and 60 °C for Mo2N cathodic catalyst. d, Photograph of the zero-gap membrane flow electrolyser with Mo2N cathode, showing that 3 L H2 was obtained after 1050 s at 1 A cm−2 and 60 °C.
