Hydrogenation of Multi‐walled Carbon Nanotubes in Ethylenediamine

Abstract

Multi‐walled carbon nanotubes (MWNTs) were hydrogenated by using lithium in ethylenediamine under Benkeser's conditions, which is convenient due to the avoidance of liquid ammonia used in the classical Birch reaction. The hydrogenated MWNTs were characterized by Raman, infrared spectroscopy, transmission electron microscopy and thermogravimetric analysis. The hydrogenation degree was also studied.
