From: Near-Unity Nitrate to Ammonia conversion via reactant enrichment at the solid-liquid interface
a Mott-Schottky plots of Ag-MoS2, MoS2, and W-MoS2 catalysts. b The non-Faradaic capacitance-potential curves for the diverse catalysts. The potential of zero charge (PZC) describes the condition when the capacitance on a surface is minimal. c The fitted surface capacitance of the three catalysts. d The peak intensity of absorbed NO3– from in situ Raman spectra of catalysts at various potentials. e Bode plots of catalysts at the reduction potential of − 0.6 V versus RHE in 10 mM NO3– electrolyte. f The ECSA normalized NO3‒ adsorption capacity at different applied potentials on catalysts.
