| Abstract: | High-quality single-walled carbon nanotubes were synthesized by catalytic chemical vapor deposition using Co/Mo as a catalyst at 850℃under the mixture of methane, argon and hydrogen gas. FE-SEM, HR-TEM, and Raman spectroscopy were used to characterize the products. The influences of the deposition temperature, flow rate of methane, and hydrogen-prereducing on the products were investigated. The optimum preparation parameters were obtained. |
