The reductive dechlorination mechanism of benzenyltrichloride at an Ag cathode was investigated using cyclic voltammetry (CV) and potentiostatic electrolysis, in CH3CN solvent containing 0.1 mol·L- tetrabutylammonium perchlorate (TBAP). The adsorption of Cl- generated during dechlorination was detected using wide anode region CV, based on its anodic reaction with Ag. The CV results indicated that: (1) Ag exhibited better electrocatalytic activity than Hg for the dechlorination; (2) the first reduction peak, which was divided from the reduction peak of benzenyltrichloride at -1.19 V (vs Ag/Ag+) when the scan rate was ≤50 mV·s-1, is an adsorption controlled process and its electron transfer occurred in a concerted way, and the electron transfer coefficient is approximately 0.25; (3) the potential region where departing Cladsorbed on Ag ranged from -0.75 to -1.75 V (vs Ag/Ag+ ). The electrolysis results indicated that dechlorination product selectivity was strongly dependent on the Ag electrode potential.
