Figure 2From: Two novel hierarchical homogeneous nanoarchitectures of TiO2 nanorods branched and P25-coated TiO2 nanotube arrays and their photocurrent performances FESEM images of (a) top view, (b) cross-section view, (c) high-magnification top view of BTs. (d) TEM image of a typical individual branched TiO2 nanotube shown in (a); insets are its SAED and HRTEM images of the marked areas, respectively.Back to article page
