From: Facile Synthesis and Tensile Behavior of TiO2 One-Dimensional Nanostructures
SEM images of as-synthesized nanostructures on a Ti grid recorded at low (a) and high (b) magnifications, respectively. The inset in a shows a bare Ti grid before reaction. c A micro-Raman spectrum shows three peaks at 224, 444, and 607 cm −1, corresponding to the Raman active modes B1g, Eg and A1g of rutile TiO2, respectively. d A XRD spectrum shows diffraction peaks, most of which could be indexed to rutile TiO2. The higher intensity background recorded before the (110) peak was contributed from the glass slide used to hold the samples. e A low magnification TEM image shows a catalytic material on the tip of a nanostructure. f A high magnification TEM image shows a part of one nanostructure. The FFT pattern demonstrates the single crystalline nature of the nanostructure. The lattice fringes in the inset have a neighboring spacing of 0.358 nm, close to the d -spacing of (110) plane of rutile TiO2. The growth direction of the nanostructure is close to the [210] direction
