Performance of the NTP-ERR system in synthesizing NH₃. (a, b) LSV curves. Ammonia production rate and Faraday efficiency of (c) Cu; (d) CuRu_0.1; (e) CuRu_0.5; (f) Ru. (g) Optimal potential of Cu, Ru, and their nanoalloys relative to RHE when the production rate of ammonia or the Faraday efficiency of ammonia is taken as the evaluation standard. (All data points represent the mean ± standard deviation (SD) of three independent experiments using different batches of catalysts. The maximum FE of 98.3% is the average of three measurements under identical conditions.)
