Nitrogen-containing functional groups
WebbWhen the OCNTs were treated in the medium temperature range between 300 °C to 500 °C, mainly pyridine -type nitrogen groups were generated, whereas pyridinic, pyrrolic and quaternary-type nitrogen groups were the dominating species present on the CNT surface when treated above 500 °C. WebbBoth nitrile and nitro groups contain nitrogen atoms, and they can be easily confused. Nitrile has a C≡N triple bond, and therefore can only be at the end of a structure, while nitro (NO 2) can be in any position on the carbon chain or ring. Amine is the organic derivative of ammonia, NH 3.
