| Abstract: | Using anodic oxidation in HF+ACOH+PEG solution at the constant voltage to deal with the titanium foil,the high-density TiO2 nanotube arrays with regular and orderly structure were prepared.The morphology of the nanotubes was characterized by SEM,and the crystal of the nanotubes was analyzed by XRD.The effect of oxidation time on the morphology and size of nanotube arrays were studied,and the current-time curve was obtained.The photocatalytic activities were evaluated by degradation of chloramine phosphorus.... |
