N-doped CNT/Biomineral Core/Shell Nanowires via Biomimetic Mineralization |
초록 |
We report an efficient and environmentally benign biomimetic mineralization of various minerals (SiO2, CaCo3 and TiO2) at graphitic carbon surface, which successfully created an ideal mineral/carbon hybrid structure without any harsh surface treatment or interfacial adhesive layer. The N-doped sites at carbon nanotubes (CNTs) successfully nucleated the high yield biomimetic deposition of uniform-thick mineral nanoshell in the neutral pH aqueous media at ambient pressure and temperature and generated in ‘N-doped CNT (NCNT)/mineral core/shell nanowires’. Unlike previously known organic biomineralization templates, such as protein or peptides, the electro-conductive and high temperature stable NCNT backbone enabled high temperature thermal treatment and corresponding crystal structure transformation of TiO2 nanoshell into Anatase or Rutile phase for optimized material properties. |
