Influence of Deposition Time on the Surface Morphology and Photoelectrochemical Properties of Copper Doped Titania Nanotubes Prepared by Electrodeposition

摘要

A great attention has focused on Cu doped titania nanotubes (Cu/TiNT) as a versatile advance material since it can be employed in various promising techno logical applications. The current study reported on the influence of various deposition times on the surface morphology and photoelectrochemical properties of Cu/TiNT via electrodeposition technique. Cu loaded on the TiNT surface was detected with prolonged deposition time. For photoelectrochemical (PEC) measurement, the highest responsive photocurrent density was obtained at 20 minutes with 54.3 μA/cm~2. Too long duration (40 mins) resulted in poor performance of Cu/TiNT as only 22.6 μA/cm~2 of photocurrent being generated.
