Growth of SWNTs using Cu(NO3)2 and CuO a systematic study on role of oxygen in growth of CNTs

We report an another unconventional growth of dense network Single Wall Carbon Nanotube (SCNTs) and Highly aligned Carbon Nanotubes using Cu(NO₃)₂ and CuO as catalyst. A systematic study for effects of oxygen on catalytic quality of Copper and on CNTs growth also studied. All reactions are performed in atmospheric pressure in thermal CVD chamber. The CNTs are characterized using HRSEM and micro-Raman. The ID/IG ratio and RBM peaks in raman spectra shows that grown CNTs are less defective SWNTs.
