TiO2 rutile–anatase core–shell nanorod and nanotube arrays for photocatalytic applications

Morphology-controllable polycrystalline TiO2 nanorod arrays for efficient charge collection in dye-sensitized solar cells

“…improved dye-loading amount) as observed in Fig.S5 and Fig.S6 and as reported previously [56]. As shown in Fig.4(d) surrounded by tiny single-crystalline nanorods at many places marked with yellow circles, which was also reported by Pan et al [39]. The observed τ r increase might be due to the intrinsic electronic property of the nanotube geometry.…”

“…Currently, oriented rutile TiO 2 nanorod arrays (NRAs) derived by wet chemical routes have attracted more and more attentions [36][37][38][39][40][41][42][43][44][45][46][47][48], mainly due to the intrinsic electronic properties of their single-crystalline nanostructures [49]. In 2008, Feng et al, [36] for the first time prepared densely-packed rutile TiO 2 NRAs up to 5 µm directly on a FTO substrate via a low-temperature (at 180 o C) solvothermal reaction.…”

Quasi-one-dimensional metal-oxide-based heterostructural gas-sensing materials: A review

“…Nanowires [90][91][92], nanofibers [93][94][95] and nanorods [96][97][98] have been grown successfully, starting from both vapor phase and solution phase. In the vapor phase growth process, the raw materials will firstly be evaporated and then condense on the surface of catalyst particles or lattice-matching substrates, which are automatically directed by the minimization of surface free energy [42,46].…”

Hierarchical‐Structured Anatase‐Titania/Cellulose Composite Sheet with High Photocatalytic Performance and Antibacterial Activity

“…Anatase-phase titania matters generally exhibit excellent photocatalytic activities due to the presence of more active surface sites, resulting in a higher absorptive affinity for organic substances and a lower rate of recombination. [46] The photocatalytic activities of the present anatase-titania/cellulose composite sheets were evaluated by carrying out the photodegradation of methylene blue dye in aqueous solution (10.0 mg L À1 ) under UV-light irradiation. The results are exhibited in Figure 4, where C 0 is the initial concentration of the dye solution, and C is the concentration of the dye at the time t. It was observed that the anatase-titania/cellulose composite sheets show excellent photocatalytic activities towards photodegradation of methylene blue.…”
