Web2.16.2.4.1 Poisoning. The fundamental reason for catalyst poisoning is the interaction between a component existing within the feed or product and the active sites of the catalyst. In this respect, poisoning is a chemical phenomenon, whose severity is positively correlated with time (Fig. 10 ). WebThe use of sulfur-based ligands to stabilise palladium nanoparticles usually restricts their use as potential catalysts due to the poisoning effect of sulfur . However, this effect is not universal. For example, dodecylthiolate-stabilised palladium nanoparticles have been shown to be active catalysts for the formation of carbon nanotubes .
