Nitrogen and sulfur co-doped fibrous-like carbon electrocatalyst derived from conductive polymers for highly active oxygen reduction catalysis

•Conductive polymers PEDOT and PANI are sequentially coated on silica nanoparticles.•Carbonization produced N and S co-doped highly entangled fibrous carbon.•N and S co-doped highly entangled fibrous carbon showed outstanding ORR performance comparable to Pt/C in basic condition.
