“…As in previous reports, [11][12][13] no particular variations of nanoscale properties have been observed while varying the anodization conditions. Bundles made of tightly packed tubes with diameters in the 15-40 nm range with an average around 25 nm were observed by SEM imaging.…”

“…9 In 2005 Nakayama et al reported that titania nanotubes can be obtained by anodization in a perchloric acid solution. 10 Our group recently investigated the rapid synthesis of high-aspect-ratio titania nanotubes by anodization in chloride-containing organic and inorganic acid solutions at voltages lower than 20 V. 11 The formation of titania nanotubes using both perchlorate ͑ClO 4 − ͒ and chloride ͑Cl − ͒ solutions and relatively high voltages ͑over 30 V͒ was further explored by Hahn et al 12 The present work's main purpose was to accomplish the systematic study of the anodization conditions and their effect on nanotube formation in chloride-containing solutions. In a previous work 13 we studied the role of acid type and of the anodization voltage.…”

We have completed a detailed experimental investigation into the recently discovered synthesis of titania nanotubes in chloride-ion-containing media. We show that the role of the chloride ions is catalytic and it has a strong effect in increasing the reactivity of the solution, while the nature of cations has no visible role. We have identified the critical parameters for optimal growth and fast production of nanotubes, and a basic growth mechanism for the tubes is proposed. This opens routes for significant improvements of the method toward uniformity and/or better overall yield, making it a viable alternative to the present established methods.

“…Furthermore, also some chloride or perchlorate containing electrolytes 134,154,155 can be used to grow anodic TiO 2 nanotubes -however, this type of tubes typically grows in the form of bundles on the Ti surface (see Figure 6.g) 156,157 . These tubes usually can reach few tens to few hundreds micrometer length within tens of seconds.…”

“…22 Consequently, additional crystallization is always required for those TDNTs since their photocatlytic performance is closely related to crystallinity. 2,18,20 Although bulk materials of N-doped TiO 2 have been extensively investigated for visible-light photocatalysis, [9][10][11]13,14,17 the feasible nitridization of TDNTs for syntheses of N-TDNTs is still a critical challenge. The most widespread nitriding route centres on ammonolysis of TDNTs in flowing ammonia gas at high temperature, but this process drastically damages the TDNTs due to sintering and collapse.…”
