Figure 11. (A) Cu-sag led catalytic reaction at different potentials; (B) Oulse adjusts the catalyst structure: the pulsed electrolysis (upper panel); evolution of Cu valence state under pulse reaction conditions (lower panel)[79]; (C) Enrichment of NO3- by pulsed voltage: Comparison of NO3- concentration under constant potential and pulse potential; Comparison of FE and yield under constant potential and pulse potential[75]. FE: Faradaic efficiency.
