发帖数: 219 | 1 For the flame synthesis of carbon nanotubes, can the CNT react easily with
oxygen? I noticed that people pass inert gases through the reactor after the
test as the cooling gas in many research. My concern are:
1. I am not clear about the chemical properties of carbon nanotubes, and
neither can I find the related literature.
2. Assuming that it can be oxidized or even burned under the after-tests'
environment with the oxygen, how can it survive during the test where the
exit of oxygen is unavoida |

发帖数: 219 | 3 That dosnt make sense: diamond is also carbon.
What I doubt is whether CNT is active with oxygen or not.
Another point : is there any test to verify its phenomena? Do you have such
experience?
And how about my second question? |

多读读文献吧，CNT的review一堆一堆的

发帖数: 219 | 6 I am definitely not chemisty guy. I have read 30+ journals & review. No one
showed this detail. Maybe they think it is only a small piece of cake, but
not for me?
And, could you please tell how to explain my second question?

发帖数: 120 | 7 你的是啥反应环境啊？
用载气当然可以抑制氧化反应
反应也要考虑动力学啊，光考虑热力学是不是可行是不够的

发帖数: 219 | 8 that makes sense.
I just hate making this kind of swift for different gases during the test.
Base on my equipment it will be a nightmare for me, though I have to do.
I will keep on learning, and maybe a chemist some day.^_^
Thanks a lot.

发帖数: 6055 | 11 do you have chance to do TGA?
if so, do an TGA in pure oxygen, then in air, and then in any oxygen
concentration you want. compare the results

发帖数: 219 | 12 Not yet, that is why I need your help theoretically, and better if there is
some evident experiments done.
Anyway, I can try with that treatment after tests.
Thanks ~~
