Abstract

Abstract: Development of efficient electrocatalysts for oxygen reduction reaction (ORR) from resource‐abundant, eco‐friendly, and low‐cost materials is important for environmental‐friendly fuel cells. In this work, N, P, S/Fe‐codoped carbon (FBC−Fe) with hierarchical porous structure was successfully prepared by the simple pyrolysis of feculae bombycis (FB) in the presence of ferric nitrate and followed by an acid etching process. FBC−Fe exhibits an excellent long‐term durability and a remarkable methanol‐resistance as well as a high electrocatalytic activity (Eonset : 0.92 V vs RHE, E1/2 : 0.81 vs RHE, and electron transfer number: 4.1) comparable to commercial platinum–carbon (Pt/C, 20 wt.%) catalysts for the ORR in alkaline media. This low‐cost and simple approach provides a straightforward route to synthesize excellent electrocatalysts for ORR from biomass. Abstract : N, P, S/Fe‐codoped porous carbon with unique hierarchical porous structure and high surface area was prepared from biomass feculae bombycis (FB) and exhibits a high electrocatalytic activity for the ORR in alkaline media.
