METHOD OF FABRICATING CARBON NANOTUBES UNIFORMLY COATED WITH TITANIUM DIOXIDE

摘要

Provided is CNTs on which TiO<SUB>2</SUB> is uniformly coated. The method includes: functionalizing CNTs with hydrophilic functional groups; mixing the CNTs functionalized with hydrophilic functional groups in a solution that contains with TiO<SUB>2</SUB> precursors; refining TiO<SUB>2</SUB> precursor-coated CNTs from the solution in which the CNTs and the TiO<SUB>2</SUB> precursors are mixed; and heat treating the refined TiO<SUB>2</SUB>-coated CNTs. The TiO<SUB>2</SUB>-coated CNTs formed in this manner simultaneously retain the characteristics of CNTs and TiO<SUB>2</SUB> nanowires, and thus, can be applied to solar cells, field emission display devices, gas sensors, or optical catalysts.
