| Abstract: | In this paper, nano- scale Pd/Cu particles were electrodeposited simultaneously on glassy carbon electrode （GCE）. Cyclic vohammetry was adopted to study the electrochemical reduction of carbon tetrachloride （CT） on glassy carbon electrode electrodeposited with Pd/Cu nano - scale bimetallic particles. The effects of scale of nano - particles and Pd to Cu ratio on the CT reductive dechlorination were investigated. The mechanism of the reactions was also discussed. |
