a FE ratios of C4H6 to C2H4 at different concentrations. b, c Potential-dependent current densities and FEs of the obtained products over the Cu-NAs and Cu-12SH-NAs under 80% C2H2. d LSV curves of different catalysts. DEMS signals for C2H4 and C4H6 of the Cu NAs (e) and Cu-12SH-NAs (f) in LSV mode. The insets are partial enlarged detail of the onset potentials (g) DEMS signals for C4H6 of the Cu NAs and Cu-12SH-NAs under square wave potentials. All “a.u.” represents arbitrary units. h Continuous tests of the Cu-12SH-NAs catalyst for the EAH process for 13 h. The error bars correspond to the standard deviation of at least three independent measurements. Source data are provided as a Source Data file.
