摘要：

Highly ordered ZrO2 nanotube arrays have been fabricated by anodization at different voltages between 20-50 V. Photoluminescence of the as-prepared freestanding ZrO2 membrane were tested and photocatalytic activities of Zr02 nanotube arrays were characterized by quantifying the degradation of methyl orange dye solution. It was found that the as-prepared samples exhibited two types of photoluminescence peaks, one is stable peaks and another is unstable peaks which shift with the excitation wavelength. In the samples annealed at 400 degrees C, only stable peaks are presented. The decolorization percentage decreases with a higher solution concentration, while increases with a larger diameter of ZrO2 nanotubes. (C) 2013 Elsevier B.V. All rights reserved.
