We present the first synthesis of double coaxial carbon nanotubes with nitrogen-doped and boron-doped multiwalls by the template technique with two-step chemical vapor deposition. X-ray photoelectron spectra confirm the coaxial formation of different-doped structures. The electrical conductance and oxygen chemisorption measurement indicate dual electrical properties and chemical activity at their outer and inner layers.
