The electrochemical synthesis of nitrogen-containing molecules from biomass-derived compounds under ambient conditions is demonstrated, relying only on green sources feedstock, renewable energy, and water. In this study, we report a two-step method electrochemically synthesizing 5-(aminomethyl)furan-2-carboxylic acid (AFCA) 5-hydroxymethylfurfural (HMF) using hydroxylamine (NH2OH) as the nitrogen source in an acidic electrolyte. first step, HMF was reductively aminated into (5-(aminomethyl)furan-2-yl)methanol (HMFA) NH2OH nitrogen. This followed by second involving oxidation HMFA to AFCA manganese oxide (MnOx) anode at same pH. MnOx able selectively oxidize alcohol group produce with 35% Faradaic efficiency without affecting amine group. As both these reactions are completed pH 1 electrolyte, it eliminates need separate before proceeding reaction. Among different metal electrodes (Ag, Au, Cu, Pb, Pt Sn) tested for reductive amination reaction, Ag displayed best performance aminate intermediate species, HMFA, up 69% mild potentials −0.50 VRHE. Density functional theory calculations were carried out explore possible reaction pathway Ag(111), which suggests thermodynamically feasible even 0 cathodic experimental parameters optimized reveal that electrolyte optimal Our work shapes future possibility any product separation between steps combining cathode sharing Since involve four electrons transferred, half single reactor can eliminate energy-wasting auxiliary counter such hydrogen evolution or water oxidation.
