Photocatalytic reductive dechlorination of chlorobenzene to benzene in 2-propanol suspension of metal-loaded titanium(IV) oxide nanocrystals in the presence of dissolved sodium hydroxide.

Photocatalytic reaction of chlorobenzene in 2-propanol suspension of palladium- and rhodium-loaded titanium(IV) oxide nanocrystals in the presence of dissolved sodium hydroxide under deaerated conditions, in which 2-propanol, metal loaded (palladium and rhodium) and sodium hydroxide effectively acted as hole scavenger, co-catalyst and chloride solidifier, respectively, quantitatively gave benzene and chloride ions with a high stoichiometry.
