Fig. 6: Mechanistic study on NO3– electroreduction.
From: Near-Unity Nitrate to Ammonia conversion via reactant enrichment at the solid-liquid interface
a In situ ATR-IR spectra of Ag-MoS2. The Si-O signal was derived from the reduction of surface SiO2 on the Si semi-cylindrical prism substrate under the applied potentials. b Online differential electrochemical mass spectrometry (DEMS) measurements of NO3RR over Ag-MoS2 under the potential of −0.6 V versus RHE. Electronic band structures of (c) MoS2 and (d) Ag-MoS2. e Gibbs free energy diagram of various intermediates generated during NO3RR over Ag-MoS2 at pH = 7.
