A facile hydrothermal synthesis and properties of TiO₂ nanosheet array films

Abstract

A facile hydrothermal procedure was adopted to prepare TiO 2 nanosheet array film on Ti foil, with NaCl as a morphology control agent. SEM, EDS, XPS and XRD showed that the TiO 2 nanosheets with uniform morphology were vertically grown on the surface of Ti foil, and the nanosheets were interlaced with each other. When the hydrothermal reaction was controlled at 140°C for 6 h, TiO 2 nanosheet array film with superhydrophilicity (water contact angle of 3°) was obtained. In addition, excellent flexibility of Ti foil with TiO 2 nanosheet array films could be a promising material for flexible application.

Titanium Dioxide Nanosheets derived from Indonesian Ilmenite Mineral through Post-Hydrothermal Process

“…The hydrothermal technique was used for the formation of the desired TiO2 nanosheets because it is easy, inexpensive, and environmentally friendly 9,10) . Furthermore, it has the bandgap energy (Eg) closer to the TiO2 bulk value of 3.20 eV, which facilitates the electron excitation under the visible light exposure 11) and enhances its photocatalytic performance A previous study was carried out using the commercial precursor P25 Degussa nanoparticles to produce TiO2 nanosheets 12) .…”

Preparation and Electrochemical Properties of Flow-Through TiO₂ Nanoarray

“…TiO2 nanoarray electrodes are particularly attractive due to more feasible electron transfer through its space charge layer [18]. The preparation methods of TiO2 nanoarrays include template method, hydrothermal method and anodization method [19]. TiO2 nanotube and nanopore arrays can been well fabricated by anodization process [20].…”
