WebDechlorination Hydrogen-catalyzed dechlorination is an emerging methodology for the low-energy treatment of a range of chlorinated waste streams that involve the selective cleavage of one or more C–Cl bonds, reducing toxicity and generating reusable raw material. Vicinal reduction involves the removal of two halogen atoms that are adjacent on the same alkane or alkene, leading to the formation of an additional carbon-carbon bond. Biological reductive dechlorination is often effected by certain species of bacteria. Sometimes the bacterial species are highly specialized for organochlorine respiration and even a particular electron donor, as in the case of Dehalococcoides and Dehalobacter. In other examples, such a…
