Abstract-In this study, we attempt to synthesize nanosized titanium dioxide with tubular structure for the photocatalytic applications, and self-prepared anatase TiO 2 powder is the precursor. We demonstrated that nanosized TiO 2 with tubular structure could be synthesized with a NaOH hydrothermal treatment on TiO 2 powder and then with a subsequent acid washing. Furthermore different formation mechanism of nanotubes could be got by controlling the pH value of acid washing step. In this research, we investigate the influence of different pH values of acid washing on the crystalline-structure, optical absorption range, porosity, specific surface area, and photo-catalytic activity of nanotubes. The influence of the preparation methods on crystalline-structure of photocatalysts and activities of photocatalytic reaction are obvious. The experimental results show that anatase TiO 2 nanotubes are produced as the pH value of acid washing is decreased to 1.3. Under this condition, the outer diameter and length of the nanotube is about 10 nm and 1μm respectively, its group is like petals. And it possesses the largest surface area of 381.2 m 2 /g, band gap of 3.12eV and the best photocatalytic activity.Index Terms-Anatase, hydrothermal method, photocatalytic activity, titanium dioxide nanotube.

Here, we intend to review those patents related with the technology of dye sensitized solar cells. In particular we discuss patents and papers that enable metal oxide layer to be more controllable and feasible for applications, and new and innovative dyes, sensitizers and electrolytes with promising features. Finally various methods were reviewed for fabricating semiconductor layers and complete DSSC devices focusing on the mass production of photovoltaic cells.

“…In order to convert TiO 2 into PTO, lead acetate precursor has been typically used. However, the precursor solution cannot fill the NT channels, in particular, deep inside of the channels, by only capillary force since the bottom‐ends of conventional TiO 2 NTs are closed . This phenomenon may result in incomplete conversion.…”

Here, we demonstrate a novel process to convert TiO 2 nanotubes into ferroelectric nanohoneycombs, comprised of vertically aligned PbTiO 3 nanotubes. Tube bottom opening process enabled effective infiltration of lead acetate precursor into the nanotubes. Nanohoneycombs, which were converted via additional lead supplement process, showed uniform conversion and well-defined ferroelectric properties with the effective piezoelectric coefficient of approximately 20 pm/V, which was measured by piezoresponse force microscopy.
