Figure 2. Morphological and phase characterization of TiO2/Ni(OH)2 core/shell nanorod arrays.
(a, b) SEM images at different magnifications. Inset in (a) is a side view of the array. (c, d) TEM images of the heterostructured nanorods (SAED pattern in inset). (e) TEM image of the nanoflake shell (HRTEM image in inset). (f) EDS elemental mappings of Ti and Ni.
