摘要：

A study was conducted to investigate the influence of water vapor on the formation of single-walled carbon nanotubes (SWCNT) in laser ablation. The SWCNTs were synthesized, using a furnace-based laser ablation process, while the evaporation of the target was driven by a Nd:YAG laser. It was found that the ternary catalyst was composed from nickel, cobalt, and molybdenum and the oven temperature was maintained at 1200 °C in each test. All the investigations were performed in a N2 atmosphere at a pressure of 101 kPa and a gas flow rate of 0.4 slpm. The water vapor was controlled through mass flow controllers from 3-2063 ppm. N2 saturated with water vapor was achieved by bubbling it through a stainless steel scrubber. The products generated under the investigations were collected on a water-cooled copper finger behind the target.
