| Abstract: | In this work, the combination of the advantages of two-phase catalysis, electrocatalysis and colloid catalysis is presented. It is shown that palladium or gold colloids prepared by citrate reduction can be charged negatively in a heterogeneous two-phase reaction and subsequently used as aqueous catalysts for dehalogenation reactions. This can be regarded as a new type of electrocatalysis. |
