Abstract
Herein, we report, for the first time, application of Ag nanowire array electrodes for electrocatalytic reduction of chloroform in an aqueous solution of 0.05 M KClO4. The activity of this electrode was compared with a bulk Ag electrode, and the peak potential shifted up to 280 mV to less negative values, suggesting improved catalytic properties toward the reduction of chloroform. The template-assisted potentiostatic electrodeposition of Ag nanowires from a cyanide-based solution was optimized. Particularly, the influence of working electrode potential and duration of electrodeposition on the length of nanowires, passed electric charge, pore-filling rate, and current efficiency was studied. A highly reproducible and fast fabrication of anodic alumina templates was achieved by optimizing operating parameters of the voltage pulse detachment and duration of wet chemical etching.
