Fabrication and structural characteristics of ordered TiO2-Ru(-RuO2) nanorods in porous anodic alumina films on ITO/glass substrate
Ordered nanorod (similar tophi50 nm) arrays of TiO2-Ru and TiO2-RuO2 embedded in porous alumina films were prepared from sputtered Al/ITO films on glass substrates through successive processes of anodization and cathodic electrodeposition. The microstructure of the nanorod arrays was investigated by field-emission scanning electron microscopy and transmission electron microscopy, and the chemical states of the titanium and ruthenium elements in the nanorods were analyzed through X-ray photoelectron spectroscopy. The as-electrodeposited nanorods are composed of ruthenium metal and amorphous titanium(IV) oxide/hydroxide, while the nanorods after being heated at 600 degreesC for 2 h are polycrystalline and composed of nano-crystals (5-20 nm across) of tetragonal anatase TiO2 and cubic RuO2.
