The presence of water in lithium mediated ammonia synthesis has previously been shown to have a significant impact on the Faradaic efficiency. By drying the carbon cathode overnight (0 mbar, 40 °C), a significant increase in Faradaic efficiency was measured; from 17 % ± 0.5 % (three repeats) to 33.5 % ± 1.5 % (two repeats) at -6 mA cm - 2 geo with 0.25 vol. % EtOH. Drying the carbon cathode also resulted in an increased proportion of ammonia produced in the gas phase, up to 50 %. Understanding the cause for these preliminary findings will be the focus of future work.
