摘要

For the first time iridium oxide (IrO_2) nanotubes are synthesized by electrodeposition in a polycarbonate (PC) template. Potential cycling (90 cycles) between 0.0 and 0.9V is used for the preparation of IrO_x nanotubes onto the PC template with a pore diameter of 100nm. Field-emission scanning electron microscopy (FESEM) images show, that IrO_2 nanotubes with uniform diameters of 110±10nm and an estimated length of 1-3μm are formed. The electrochemical properties and the electrocatalytic activity of a glassy carbon-IrO_x nanotube modified electrode toward Cr~(3+) and As~(3+) oxidation are investigated. Finally, the modified electrode is used for micromolar detection of the proposed analytes using differential pulse voltammetry.
