Abstract
| - Carbon nanofibers (CNFs) are treated with ammonia at elevated temperatures to generate pyridinic-type basicspecies on the CNFs surface. The basic species act as anchors for Pd nanoparticles, resulting in good dispersionand stability of the Pd nanoparticles. These ammonia-treated carbon nanofibers as Pd supports have beenused for catalytic hydrodechlorination. It shows high activity and impressive time-on-stream stability in thegas- and liquid-phase catalytic hydrodechlorination of chlorobenzene. The presence of pyridine-type specieshelps to remove the byproduct HCl from the Pd catalyst, thus preventing the inhibition effect of HCl. It alsokeeps Pd nanoparticles from aggregation, which is another reason for catalyst deactivation.
