Tungsten-Based Ternary Catalysts for Selective Growth of Single-Walled Carbon Nanotubes

Key Points

• The aim is to explore tungsten-based ternary catalysts for synthesizing single-walled carbon nanotubes with controlled diameters.
• Used a supported catalytic chemical vapor deposition process
• Employed a Fe-Mo-W ternary catalyst system
• Synthesized SWCNTs with diameters between 1.5 and 3 nm
• Achieved controlled synthesis of single-walled carbon nanotubes
• Diameters were successfully maintained within the 1.5 to 3 nm range
• Demonstrated the effectiveness of the tungsten-based catalyst system
