Electrochemical Preparation of Bismuth Nanowires Using Ion-Etched Porous Polycarbonate Membrane

Bismuth as “environmentally friendly” metal represents a promising electrode material for different electrochemical techniques. In this study, we prepared bismuth nanowires by chronoamperometry using ion-etched porous polycarbonate membrane. According to SEM- EDX analysis, obtained bismuth nanowires show uniform growth with a high aspect ratio. Due to its large surface, these nanowires have the potential to greatly improve sensor properties for the detection of a variety of inorganic and organic compounds (pollutants, drugs, etc.).
