Since the discovery of carbon nanotubes (CNT), this material has been recognized as an attractive material because of its exceptional physical and chemical properties. CNT must be functionalized for most applications. However, the functional groups on the CNT are very complex. Here a simple acid–base titration is introduced to characterize the functionalized multi-wall carbon nanotubes (MWCNT). By...
Point of zero charge is a useful measurement to assess the surface acidity of multi-walled carbon nanotubes and to characterize functional groups on the multi-walled carbon nanotube surface. Knowledge of point of zero charge also assists the choice of an appropriate metal precursor to be used for electrostatic adsorption to prepare metal particles supported on multi-walled carbon nanotubes. Multi-walled...
