The efficient ORR/OER bifunctional electrocatalytic activity and long-term durability of the obtained composite might be attributed to the characteristic honeycomb-like porous structure with sufficient accessible active sites, the synergistic effect of FeS and Fe 3 C, and the N,S codoped porous carbon, which provides a promising application ... WebIn addition, when using unifunctional ORR or OER electrocatalysts as air electrodes, like noble metal catalysts (Pt/C or Ru/IrO 2), there are the disadvantages of high cost and poor stability. Therefore, rational design …
