Combining efficiently catalytic hydrodechlorination and wet peroxide oxidation (HDC–CWPO) for the abatement of organochlorinated water pollutants.

Highlights: [•] The two-step reaction (HDC–CWPO) represents an efficient solution for chlorophenols breakdown. [•] A short-time HDC step before CWPO improves the rate of mineralization. [•] Complete dechlorination of chlorophenols and a high mineralization (80%) was reached. [•] The effluents obtained upon HDC–CWPO process presented negligible ecotoxicity values (<0.5TU). [•] Both HDC (Pd/γ-Al2O3) and CWPO (Fe/γ-Al2O3) catalysts showed a highly stable performance. [Copyright &y& Elsevier]
