Aqueous-phase hydrodechlorination of chlorophenols with pillared clays-supported Pt, Pd and Rh catalysts

- Rh catalyst showed the highest activity in 4-CP dechlorination and hydrogenation.
- Optimal catalysts reduction temperature between 90 °C and 200 °C was found for 4-CP HDC.
- Rh catalyst allowed complete dechlorination of polychlorinated phenols.
- Pd and Rh catalysts showed high stability in long-term experiments.
- Pt catalyst suffered deactivation due to adsorption of chlorinated organic species.
