Dechlorination of chlorophenols mediated by carbon nanotubes in the presence of oxygen

摘要

Using chlorophenols as probe compounds, we examined the occurrence of oxidative coupling during carbon nanotube adsorption of phenolic compounds in the presence of oxygen. The oxidative coupling was confirmed by the agreement of the dechlorination stoichiometrics of various chlorophenols with the free-radical mechanism of oxidative coupling. The oxidative coupling reaction was first-order with respect to chlorophenols on carbon nanotubes and increased with the increase of pH.
