ABSTRACT A thin film TiO 2 in hierarchical nano-structure with high photocatalytic activities was synthesized in simple steps with ultrasonication. The crystal structure and morphology of the photocatalyst were investigated by X-ray diffraction (XRD) and high-resolution field emission scanning electron microscope (FE-SEM). In the present work, nanostructured TiO 2 was directly formed onto a Ti substrate via a solution approach. Th...

ABSTRACT A commercially pure titanium sheet precipitated TiC in the surface layer was fabricated by anodic oxidation in NH 4 NO 3 solution and heat treatment in air. The fabricated sheet showed relatively high photocatalytic activity in 0.1 M KI solution, which was clo...
