Sulfur-doped iron-cobalt tannate nanorods (S-FeCoTA) derived from metal-organic frameworks (MOFs) as electrocatalysts were synthesized via a one-step hydrothermal method. The optimized S-FeCoTA was interlaced by loose nanorods, which had many voids. The S-FeCoTA catalysts exhibited excellent electrochemical oxygen evolution reaction (OER) performance with a low overpotential of 273 mV at 10 mA·cm-2 and a small Tafel slope of 36 mV·dec-1 in 1 mol·L-1 KOH. The potential remained at 1.48 V (vs RHE) at 10 mA·cm-2 under continuous testing for 15 h, implying that S-FeCoTA had good stability. The Faraday efficiency of S-FeCoTA was 94%. The outstanding OER activity of S-FeCoTA is attributed to the synergistic effects among S, Fe, and Co, thus promoting electron transfer, reducing the reaction kinetic barrier, and enhancing the OER performance.

Using sodium phytate (PA) as a ligand precursor, boron-doped iron-cobalt phytate materials (B-FeCoPA) were synthesized via a one-step hydrothermal method. Boron incorporation into FeCoPA effectively modulates the local bonding environment and electronic structure through synergistic B-Fe-Co interactions, thereby facilitating electron transfer and enhancing the electrocatalytic activity for the oxygen evolution reaction (OER). The optimized B-FeCoPA exhibited an outstanding OER catalytic activity in alkaline electrolyte, achieving low overpotentials of 299 mV at 10 mA·cm-2 and 354 mV at 100 mA·cm-2, a small Tafel slope of 46 mV·dec-1, and a high Faradaic efficiency of 96%. Moreover, B-FeCoPA demonstrated good operational stability, maintaining a stable potential of approximately 1.52 V (vs RHE) at 10 mA·cm-2 over a 10-h continuous test in 1.0 mol·L-1 KOH.
