Hi all,
I will begin the organic functionalization of SWNTs. I will use HiPco
type SWNTs, which is made by ourselves. For the purification, it would
need the wet air oxidation in a high temperature to remove the
amorphous carbon. However, the instrument would not available in the
near future. How about just treat the tubes with concentrated HCl?
Maybe to omit the wet air oxidation process would affect my organic
functionalization (general reactions, I mean.) step too much? Anybody
has any good idea for the purification of this kind of tubes, except
the microwave method?
Otherwise, the microwave method seems a good one, anybody had ever use
this method? And, which method is better?
Thanks in advance!
