Recent advances in preparation of novel chromatographic stationary phases with carbon nanotubes

Recent advances in preparation of novel chromatographic stationary phases with carbon nanotubes

Se Pu 31(12): 1146-1153

Carbon nanotubes (CNTs) as a new functional material have attracted the interest of scientists and engineers in analytical chemistry, due to their excellent physical, chemical and mechanical properties. The preparation of chromatographic stationary phases with CNTs has been performed by packing method or in situ catalytic chemical vapor deposition. The deposition of CNTs on a chromatographic solid matrix (e. g. silica micro-particles or organic polymer microspheres) was carried out to generate a packing material for high performance liquid chromatography. Capillary monolithic columns for liquid chromatography were also prepared by embedding CNTs in polymer monolithic columns. Columns with CNTs have the unique advantages in the separation of aromatic compounds for the tr electron system of CNTs. Herein, the recent applications of CNTs in the preparation of chromatographic stationary phases are reviewed, including gas chromatography and liquid chromatography. The future developments in this field are also prospected.
