Caption

(a) UV-Vis absorption spectra of the 0.1 M Na2SO4 electrolytes after ECNRR at different potentials for 2 h. (b) YNH3 and FEs at applied potentials in 0.1 M Na2SO4. Error bars represent calculated standard deviation from independent experiments (at least three times). (c) Comparison of the ECNRR performance of Pd-GDY with others. Error bars represent calculated standard deviation from independent experiments (at least three times). (d) 1H-15N NMR spectra of 0.1 M Na2SO4 after ECNRR under 15N2 with Pd-GDY as catalyst. (e) YNH3, FEs and corresponding UV-Vis absorption spectra (inset) of Pd-GDY and Pd NP/GDY catalysts after 2 h electrolysis at ?0.40 V. (f) Stability test of Pd-GDY at ?0.4 V in 0.1 M Na2SO4 under ambient conditions.
