Supplementary Material

The supplementary information contains details about the following aspects: (1) SEM images of nitrogen doped carbon nanotubes (N-MWCNTs) synthesized by CVD using acetone in the trap; (2) additional SEM images of N-MWCNTs synthesized by CVD when an aqueous solution of NaCl is used in the trap; (3) Diameter distribution of these N-MWCNTs; (4) Schematic array of CVD for additional experiment to verify the effect on the N-MWCNTs morphology due to the NaCl aqueous solution in the trap ; (5) Two sprayer CVD equipment; (6) N-MWCNTs fabricated by two sprayer CVD method; (7) HRTEM images of nanoparticles encapsulated in N-MWCNTs corresponding to the simple CNx-4; (8) HRTEM image of N-MWCNTs sample CNx-4.
