a Linear scan voltammetry curves of ordered CuPd nanocubes, Cu nanocubes, and Pd nanocubes normalized to the geometric area. b Partial NH3 current densities normalized to the geometric area. c FE of NH3 at different potentials, The error bars correspond to the standard deviation from three independent measurements. d NH3 yield rate of ordered CuPd nanocubes, Cu nanocubes, and Pd nanocubes at various potentials. e The yield rate of NH3 with or without nitrate at −0.6 V vs. RHE. f NMR spectrum of the products generated during the electrocatalytic NO3RR with ordered CuPd nanocubes in 1 M K15NO3 or 1 M K14NO3 at −0.5 V vs. RHE. g Stability test by running the CA measurement on the ordered CuPd nanocubes at −0.5 V vs. RHE for 12 h.
