Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>S and N co‐doped, few‐layered graphene oxide is synthesized by using pyrimidine and thiophene as precursors for the application of the oxygen reduction reaction (ORR). The dual‐doped catalyst with pyrrolic/graphitic N‐dominant structures exhibits competitive catalytic activity (10.0 mA cm⁻² kinetic‐limiting current density at −0.25 V) that is superior to that for mono N‐doped carbon nanomaterials. This is because of a synergetic effect of N and S co‐doping. Furthermore, the dual‐doped catalyst also shows an efficient four‐electron‐dominant ORR process, which has excellent methanol tolerance and improved durability in comparison to commercial Pt/C catalysts.</p> </abstract>
