Notes:
Multi-wall carbon nanotubes (MWCNTs) were used as a support for the deposition ofhighly dispersed platinum. After characterization by several physical techniques, the catalyst wasstudied in reactions for: hydrodechlorination of carbon tetrachloride and the hydrodechlorination ofdichlorodifluoromethane. For the first reaction Pt/MWCNTs were very effective catalysts in termsof both the overall activity and the selectivity to CHCl3; both quantities appeared high and stable.For CCl2F2 hydrodechlorination the catalyst was rather moderate, although very stable, activity andproduct selectivities were established at a constant level in a relatively short time-on-stream. TheMWCNTs-supported Pt particles do not undergo great changes during the reactions, i.e. neithersubstantial metal sintering occurred nor extensive surface carbonization/chloriding took place
