a The effect of NO pressure on NORR product distribution and total current density over Cu NWA at – 0.4 V versus RHE at 25 oC. b, c NH3 FE (b) and NH3 partial current density (c) over Cu NWA and commercial Cu foam at different applied potentials at 25 oC under 1 atm, 5 atm NO, respectively. d The NH3 partial current densities and corresponding NH3 yield rate of Cu NWA and Cu foam under 5 and 10 atm NO at 25 oC, respectively. e Long-term chronopotentiometry stability test of Cu NWA at 500 and 1000 mA cm–2 in 5 atm NO-saturated 1 M KOH electrolyte at 25 oC, and the electrolyte were refreshed every 10 h and 4 h. a–d Error bars were gained after at least three times independent measurements. All of the potentials were reported without iR corrected. Source data are provided as a Source Data file.
