Effect of silver or copper middle layer on the performance of palladium modified nickel foam electrodes in the 2-chlorobiphenyl dechlorination

► Dechlorination of 2-chlorobiphenyl. ► Using silver or copper as interlayer between nickel foam substrate and palladium. ► Pd and the interlayer loadings have positive effects on dechlorination. ► Increasing the current density increases the reaction rate but reduces the CE. ► The Pd/Ag/Ni electrode exhibits superior activity and stability.
