In this paper, the chemical reduction of solubilized multi-walled carbon nanotubes by LiAlH was investigated. The amide 4 groups on the nanotubes could be reduced to hydroxyl groups, which was confirmed by FTIR and XPS studies. The Raman spectroscopic investigation showed that the morphology of the nanotubes did not change after the reduction.
