Tandem dehalogenation-hydrogenation reaction of halogenoarenes as model substrates of endocrine disruptors in water: Rhodium nanoparticles in suspension vs. on silica support

Résumé

This paper focuses on the removal of mono- and poly-halogenated arenes, as modelsubstrates of endocrine disrupting compounds from aqueous effluents. The efficiency of catalysts based on metallic nanoparticles in the tandemdehalogenation-hydrogenationreaction as a pre-treatment for the remediation of organic halogenated pollutants was studied. Two catalytic systems - aqueous colloidal Rh0 dispersions and SiO2-supported Rh0nanoparticles - were easily prepared under mild conditions and were compared in the hydrodehalogenation reaction of the modelsubstrates. Interesting results in terms of catalytic activity were obtained, particularly with Rh0@SiO2 catalyst, which proved to be more stable and efficient under the reaction conditions.
