In order to improve the catalytic efficiency toward electroreduction of organic halides, Ag-exchanged Y zeolite (Ag-Y) has been prepared and modified on glass carbon (GC) electrodes. Ag-Y zeolite was characterized by XRD, BET, ICP, SEM, TEM and XPS. Silver species, in state of Ag+, has been successfully exchanged into Y zeolite. The Ag-Y zeolite modified electrode was used for the PhCH2Br reduction. Similar electrochemical behavior, besides more positive reduction potential, was obtained on Ag-Y/GC electrode as that on Ag and GC electrodes. According to the bulk electrolysis, the electrochemical dimerization and carboxylation yields on Ag-Y/GC electrode were enhanced to twice and triple as that on Ag electrode, and even 3.5 and 10 times as that on GC electrode.
