摘要：

A facile, efficient, and economical route to obtain carbon nanotube (CNT)/TiO2 coaxial nanocables with controlled shell thickness. A general method has been developed for the preparation of ID CNT/metal nanoparticle heterostructures and the corresponding CNT/TiO2/metal coaxial nanocable by using a very homogenous TiO2 as a linker. This method can also be extended to prepare other hybrid nanomaterials based on CNT/TiO2 coaxial nanocables. Multiwalled carbon nanotube with a diameter of 20-50nm were obtained through chemical vapor deposition (CVD). Excess polymer was removed through a 450-nm polycarbonate filtration membrane. The obtained solid was allowed to dry at room temperature. It was observed that the CNT/TiO2/ag coaxial nanocable modified conductive tin oxide substrate exhibits good SERs activity with Raman peak of slid 4-ATP.
