“…Carbon-based catalysts exhibit attractive properties for the selective hydrodechlorination [14], and are described elsewhere in this special issue. Regarding metal fluorides as supports, their use gives stable catalysts and allows better control of the extent of hydrodehalogenation [4,5,[8][9][10]12,13,19,20,23,24]. This aspect will be developed in this short review with emphasis on the studies carried out in our groups in Montpellier and Tarragona.…”
