| 摘要 |
The present invention relates to heterogeneous nanowires having a core-shell structure consisting of single-crystal apatite as the core and graphitic layers as the shell and to a synthesis method thereof. More specifically, the present invention relates to a method capable of producing large amounts of heterogeneous nanowires, composed of graphitic shells and apatite cores, in a reproducible manner, by preparing a substrate including an element corresponding to X of X 5 ( Y O 4 ) 3 Z which is a chemical formula for apatite, adding to the substrate a gaseous source containing an element corresponding to Y of the chemical formula, adding thereto a gaseous carbon source, and allowing these reactants to react under optimized synthesis conditions using chemical vapor deposition (CVD), and to a method capable of freely controlling the structure and size of the heterogeneous nanowires and also to heterogeneous nanowires synthesized thereby. |
