CARBON NANOTUBE COATED UNIFORMLY WITH ULTRATHIN NANOPRECISE EUROPIUM HYDROXIDE LAYER

摘要

PROBLEM TO BE SOLVED: To provide carbon nanotubes coated uniformly with ultrathin nanoprecise europium hydroxide layers, as well as a fabrication method for such europium hydroxide-coated carbon nanotubes. SOLUTION: The carbon nanotubes coated uniformly with ultrathin nanoprecise europium hydroxide layers are produced via following steps: (i) Carbon nanotubes are functionalized in concentrated nitric acid under elevated temperature condition; (ii) The obtained functionalized carbon nanotubes (f-CNT) are dispersed in diluted europium nitrate solution to make defined concentration of them; (iii) The reaction mixture is mixed and left for about two weeks at room temperature; and (iv) The obtained individual europium hydroxide coated carbon nanotubes (solids) are separated and dried.
