The products were analysed by NMR spectroscopy and ion chromatography after 30 min of potentiostatic measurements. a–c, The effect of temperature (0.5 M glycerol in 1.0 M CsOH, 0.6 V versus Ag/AgCl) (a), glycerol concentration (1.0 M CsOH, 35 °C, 0.6 V versus Ag/AgCl) (b) and potential (0.5 M glycerol in 1.0 M CsOH, 35 °C) (c) were examined. The constant parameters are indicated in parentheses. HER was performed on the cathode side using 25 cm3 min−1 argon flow, while the anolyte flow rate was 10 cm3 min−1. The error bars represent the standard deviation from the average (mean), originated from three separate measurements performed on three different Ni/Si electrodes. The missing FE is related to dihydroxyacetone, glyceraldehyde and oxygen.
