Structural and optical properties of template-assisted electrochemically deposited copper oxide nanotubes

Simple method of template based was adopted for the synthesis of copper oxide oxide nanotubes. Copper oxide nanotubes were grown in polycarbonate membrane of pore size 100 nm through dc potentiostatic electrodeposition technique. The study related to morphological, structural and optical properties was monitored using field-emission scanning electron microscopy (FE-SEM), x-ray diffraction (XRD) and UV-visible spectroscopy. The field emission scanning electron microscopy image clearly revealed the formation of free-standing copper oxide nanotubes on substrate. The x-ray diffraction and Raman analysis confirms the presence of both CuO and Cu2O compositions. From the UV-visible study, band gap energy was calculated to be 2.4 eV.
