Self-organized and highly-ordered TiO2nanotube array with disjunctive wall-hole structure has been synthesized from titanium foil by potentiostatic-galvanostatic anodization process. The morphology and microstructure of the TiO2layer depend greatly on the electrolyzing parameters and electrolyte components. TiO2formation mechanism by anodization oxidation is discussed. The crystallized TiO2/Ti nanotube electrode exhibited a significant enhancement of photoelectrochemical current response in comparison with micrometer-sized TiO2/Ti multiporous electrode. Such kind of TiO2nanotube will have many potential applications in various areas as an outstanding photoelectrochemical material.
