TLDR
The catalytic transformations of 1,2-dichlorobenzene, chlorobenzenes, 4-chlorobiphenyl, γ-hexachlorocyclohexane (Lindane), naphthalene and phenanthrene were studied over palladium on alumina in hydrogen-saturated water (Pd/Al2O3/H2) at room temperature and ambient pressure as discussed by the authors.Abstract:
The catalytic transformations of 1,2-dichlorobenzene, chlorobenzene, 4-chlorobiphenyl, γ-hexachlorocyclohexane (Lindane), naphthalene and phenanthrene were studied over palladium on alumina in hydrogen-saturated water (Pd/Al2O3/H2) at room temperature and ambient pressure. The chlorinated benzenes were rapidly hydrodechlorinated and Lindane was dehydrochlorinated to benzene. Partial or complete hydrogenation was observed for biphenyl and the polycyclic aromatic hydrocarbons. The phenanthrene ring was cleaved at the 9,10-position. In general dechlorination reactions were faster than hydrogenation reactions.read more

Designing Pd-on-Au Bimetallic Nanoparticle Catalysts for Trichloroethene Hydrodechlorination
TL;DR: The Pd-on-Au bimetallic catalyst structure provides a new synthesis approach in improving the catalytic properties of monometallic Pd materials and should be highly suitable as hydrodehalogenation and reduction catalysts for the remediation of various organic and inorganic groundwater contaminants.

Catalytic hydrodehalogenation of chlorinated ethylenes using palladium and hydrogen for the treatment of contaminated water
TL;DR: In this article, a kinetic model for the catalytic hydrodehalogenation of chlorinated ethylenes using Pd and H2 under water treatment conditions was presented, and the results showed that the transformation of PCE was first order with respect to both substrate and metal.

Catalytic hydrodechlorination of chlorophenols
TL;DR: In this paper, it was shown that complete destruction of chlorophenols by hydrodechlorination over palladium/carbon is possible under mild reaction conditions, and a 50/50 mixture of ethanol/water was used as the reaction solvent instead of ethanol.
