In situ formation of N- and Fe-doped carbon nanotube/mesoporous carbon nanocomposite with excellent activity for oxygen reduction in acidic media

Abstract

N- and Fe-doped carbon nanotube/CMK3 nanocomposite was firstly prepared by a simple procedure. The typical product shows excellent catalytic ability for oxygen reduction reaction in the acidic media.

Nonprecious Metal Catalysts for Oxygen Reduction in Heterogeneous Aqueous Systems

“…These authors found enhanced graphitization at lower temperatures caused by the presence of Mo. Finally, several other reports utilize different mixtures of metal, N, and C precursors to give active catalysts. − …”

Germanium and phosphorus co-doped carbon nanotubes with high electrocatalytic activity for oxygen reduction reaction

“…19 Carbon nanotubes have been reported as a promising material for fuel cell applications in acidic environment due to their large surface area, good thermal and chemical stability, and high electrical conductivity. 14,20 Furthermore, modifying CNTs by introducing heteroatom is known to improve their electrocatalytic activity for ORR. 11,21 Nitrogen-doped carbon nanotubes have been reported with excellent ORR electrocatalytic performance owing to the high electronegativity of N atoms.…”

Diamond@carbon-onion hybrid nanostructure as a highly promising electrocatalyst for the oxygen reduction reaction

“…10 And since then, various carbon materials, such as CNTs, graphene, and mesoporous carbon, have been derived for the substitution of Pt-based catalysts. [11][12][13] The application of tailored nanodiamonds (carbon nanoonions) towards the ORR is at the early stages, but they possess unique properties for applications in electrochemistry. 14,15 Due to the morphology of the carbon-onion structure, the outermost layer of the nano-onion connes several inner carbon layers from reactants.…”
