Oxalate-coordinated transition metal-based electrocatalysts have recently been shown to be very efficient for oxygen evolution reaction (OER). However, the role of oxalate ligands has not fully revealed. Here, effect with two −COO functional groups on surface bimetallic sulfides is Through ex situ Fourier transform infrared, X-ray diffraction, photoelectron spectroscopy, and other material characterization techniques in electrochemical techniques, it proved that suitable oxalate-coordinated FeNi sulfide (Fe–Ni3S2/OXs) best OER catalytic activity, which can attributed synergistic high-valence metal sites proton center carboxyl group oxalate. The results density theory calculation show coordination effectively optimize adsorption–dissociation performance catalyst OH– provide a adsorption center, thereby promoting Gibbs's free energy intermediates. And overpotential 260 mV (90% IR) observed at geometric current 100 mA cm–2 1 M KOH solution, strongly associated concentration support surface. its Tafel slope reaches 57 dec–1, excellent kinetics. This work reveals activity provides promising way preparation basic electrocatalysts.
