Controllable growth of core-shell carbon nanofiber arrays for highly sensitive electrochemical sensors

Abstract

Conical and cylindrical core-shell TiO2/C and TiC/C nanofiber arrays have been fabricated. The electrochemical measures suggest that conical nanofibers are more electroactive than cylindrical nanofibers for the more effective exposure edge plane. The conical TiC/C shows better electrochemical property than TiO2/C as result of inner conductive core.
