- •
M-NCNT materials are synthesised by pyrolysis of CNTs, DCDA and FeCl3 or CoCl2.
- •
As-prepared M-NCNT catalysts show lower ORR activity than Pt/C in acid solution.
- •
ORR activity increases by acid-treatment of M-NCNT catalysts and second pyrolysis.
- •
The prepared M-NCNT electrocatalysts show high stability and methanol tolerance.
