Electrocatalytic reductive dehalogenation of polyhalogenated phenols in aqueous solution on Ag electrodes

The electrocatalytic properties of Ag towards the dehalogenation of a variety of polychloro- and polybromo-phenols in basic aqueous solution have been evaluated. Experimental evidence is presented that Ag exhibited powerful electrocatalytic activity for dehalogenation of polyhalogenated phenols to less, or non-halogenated phenols.
