a Sketches of a traditional ePTFE/Cu (top) and ePTFE/NICC/Cu electrode (bottom). Current collection lines depicted in blue. b Activity distribution for an ePTFE/50 nm, an ePTFE/50 nm/NICC and an ePTFE/500 nm electrode at −200 mA cm–2. c Observed selectivity towards ethylene for the three designs at a constant potential of ~ –0.55 V vs. RHE. d Change in capacitance for the three designs after 4h-long operation at constant potential of ~ –0.55 V vs. RHE.
