Direct Synthesis of Colorful Single-Walled Carbon Nanotube Thin Films.

摘要: In floating catalyst chemical vapor deposition (FC-CVD), tuning chirality distribution and obtaining narrow of single-walled carbon nanotubes (SWCNTs) is challenging. Herein, by introducing various amount CO2 in FC-CVD using CO as a source, we have succeeded directly synthesizing SWCNT films with tunable well colors. particular, 0.25 0.37 volume percent CO2, the display green brown colors, respectively. We ascribed colors to suitable diameter SWCNTs. Additionally, optimizing reactor temperature, achieved much narrower (n,m) clustered around (11,9) extremely range (>98% between 1.2 1.5 nm). propose that may affect disproportionation nucleation modes SWCNTs, resulting SWCNTs’ ranges. Our work could provide new route for high-yield direct synthesis SWCNTs chiral...
