The construction of coupled electrolysis systems utilizing renewable energy sources for electrocatalytic nitrate reduction and sulfion oxidation reactions (NO3RR SOR), is considered a promising approach environmental remediation, ammonia production, sulfur recovery. Here, simple chemical dealloying method reported to fabricate hierarchical porous multi-metallic spinel MFe2O4 (M═Ni, Co, Fe, Mn) dual-functional electrocatalysts consisting Mn-doped NiFe2O4/CoFe2O4 heterostructure networks Ni/Co/Mn co-doped Fe3O4 nanosheet networks. excellent NO3RR with high NH3 Faradaic efficiency 95.2% at -0.80 V versus reversible hydrogen electrode (vs RHE) yield rate 608.9 µmol h-1 cm-2 -1.60 vs RHE, impressive SOR performance (100 mA [email protected] achieved MFe2O4. Key intermediates such as *NO, *NH2, are identified in the process by situ Fourier transform infrared spectroscopy (in FTIR). MFe2O4-assembled two-electrode coupling system (NO3RR||SOR) shows an ultra-low cell voltage 1.14 10 cm-2, much lower than NO3RR||OER (oxygen evolution reaction, [email protected] V), simultaneously achieving two expected targets value-added generation recovery, also demonstrating durability 18 h. This work demonstrates great potential ferrite-based catalysts remediation.
