Photocatalytic Properties of Size-Controlled Titania Nanotube Arrays
Figure 4
Effects of the applied voltage of titania nanotube arrays (TNAs) anodized for 5 h (a) on the degree of MB degradation as a (at 365 nm) with ultra-violet irradiation time, (b) on the correlation between the inner diameter and the apparent rate constant, that is, the slope of (a), and (c) on the apparent rate constant as a function of the length. The size and electric field factors of TNAs for the apparent rate constant of respective voltage regions are summarized in Table 1.
