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.
