Full metal jacket: Carbon nanotubes (CNTs) are used as templates to form well-defined anisotropic magnetic nanowires with ferromagnetic behavior at room temperature. Uniform assembly of catalytic Pt nanoparticles on the CNTs yields organic–inorganic hybrid composites that serve as 1D substrates for the preparation of magnetic CNT-supported Ni/NiO nanotubes (see picture).
