Abstract

Feasibility was demonstrated for the electrochemical activation of freons CF2ClCFCl2 (CFC113), CF3Br (FC13B1), and CF2Cl2 (CFC12) as well as CF3I using nickel complexes with azamacrocyclic and bipyridyl ligands as electron transfer mediators, permitting the reduction of freons under mild conditions at relatively low potentials. The catalytic efficiency of these complexes was determined for freon CFC113.
