One-Pot Synthesis of Titanate Nanotubes Decorated with Anatase Nanoparticles Using a Microwave-Assisted Hydrothermal Reaction
Figure 4
High-resolution transmission electron microscopy images of the titanate nanotubes decorated with anatase nanoparticles showing (a) the internal and external diameter of titanate nanotubes; the inset shows the TiO6 octahedra, arranged in a zig-zag fashion, forming the walls of the titanate nanotubes. (b) Titanate nanotubes decorated with anatase nanocrystals, (c) interlamellar distance of the nanotubes, and (d, e) crystallite planes with corresponding d-spacings of the anatase nanoparticles decorating nanotubes; the insets in (d, e) show selected-area electron diffraction patterns showing a bright spot as well as concentric circles corresponding to these planes. (f) Diameter distribution of anatase nanoparticles, showing an average particle diameter of 3.3 nm.
