a LSV curves with iR correction (i, current; R, resistance: 9.0 ± 0.6 ohm; electrode surface area: 0.25 cm2). b Faradaic efficiencies (upper panel: FECO; bottom panel: FEH2) and (c) jCO of different samples for applied potentials. Error bars stand for standard deviations. d Long-term stability and corresponding FECO of TeN2–CuN3 DAC. e The photograph of the flow cell (left) and long-term test of TeN2–CuN3 at –0.65 V (vs. RHE) (right). Error bars represent the standard deviation of three independent measurements.
