Sub-100 nm TiO₂ tubular architectures for efficient solar energy conversion

Abstract

The smaller, the better: sub-100 nm tubes showed enhancement in the performance of solar energy conversion devices.

Oxygen Vacancy‐Engineered Ti−Mo−Ni Ternary Oxide Nanotubes as Binder‐Free Supercapacitor Electrodes with Exceptional Potential Window

“…Also, the well‐ defined diffraction peaks at 2θ=25.3°, 38.43°, 48.1°, 53.07°, and 55.14° can be assigned to the (101), (112), (200), (105), and (211) planes of TiO 2 anatase phase (ICDD Card No. 01‐071‐1168), respectively . Additionally, small diffraction peaks were noticed at 27.52° and 41.42° that correspond to the (110) and (111) planes of the TiO 2 rutile phase (ICDD Card No.…”

Unbiased spontaneous solar hydrogen production using stable TiO2–CuO composite nanofiber photocatalysts

“…These results prevail that the TiO 6 octahedron in anatase was distorted in case of TiO 2 -CuO composite nanobers. 17 y Ti-O ¼ 722e À1.54946(R À 1.809) (1) Fig. 6a shows the UV-Vis absorption spectra of the fabricated nanobers.…”

“…3b shows the XRD patterns of the fabricated nano-bers annealed under different atmospheres. The XRD pattern 16,17 However, upon annealing the TiO 2 nanobers in oxygen, the peaks were observed at 2q ¼ 27.4 , 36 , and 41 , corresponding to (110), (101), and (111) facets of the rutile phase, respectively. In oxygen-rich atmosphere there is a large number of adatoms that react instantly with interstitial Ti 3+ on the surface forming TiO x islands, which act as rutile islands, resulting in a very high rate of phase transformation at lower temperature.…”

Recent advances in the use of TiO2 nanotube powder in biological, environmental, and energy applications

“…3,19,23,24 Extensive research studies have investigated the factors that govern the nanotube formation with tuned tube diameter and length. [25][26][27][28][29] The formed oxide layer structure on the metal surface mainly depends on the concentration and composition of the electrolyte solution and the applied voltage. 5,8 The effect of the electrolyte composition on the length of titania nanotubes is summarized in Fig.…”
