Localization of PdCl2 clusters supported on multi-wall carbon nanotubes (MWCNT) has been investigated using 129Xe NMR of adsorbed xenon. As-made MWCNTs with channels initially inaccessible for adsorption and ball-milled MWCNTs with the totally accessible internal surface were used as supports. The observed 129Xe NMR spectra were determined by the dynamics of xenon exchange between the aggregate pores and nanotube channels. No considerable changes of the 129Xe NMR spectrum with the concentration of supported PdCl2 were observed for the as-made MWCNT, while an additional resonance appeared for the ball-milled nanotubes. The 129Xe NMR experiments evidenced the supported species to be localized on the internal surface of the ball-milled MWCNT.
