Since its commercial production in the early twentieth century, titanium dioxide (TiO2) has
been widely used as a pigment1 and in sunscreens, 2, 3 paints, 4 ointments, toothpaste, 5 …

We review the fabrication, properties, and solar energy applications of highly ordered TiO2
nanotube arrays made by anodic oxidation of titanium in fluoride-based electrolytes. The …

Titanium dioxide nanotubes, made by anodization, are highly sensitive to hydrogen; for
example, cycling between nitrogen atmosphere and 1000ppm hydrogen a variation in …

Since material properties are structure-dependent, new and interesting properties are
expected from unusual or complex structures. Biomorphic mineralization is a technique that …

Described is a room-temperature hydrogen sensor comprised of a TiO2-nanotube array able
to recover substantially from sensor poisoning through ultraviolet (UV) photocatalytic …

This paper reviews the current work carried out on mixed-oxide systems such as SnO2–
WO3, TiO2–WO3 and SnO2–TiO2 with the ultimate aim of the application in gas sensing …

Synthesis—particularly by electrochemical anodization-, growth mechanism and chemical
sensing properties of pure, doped and mixed titania tubular arrays are reviewed. The first …

We study the influence of Nb do** on the TiO 2 anatase-to-rutile phase transition, using
combined transmission electron microscopy, Raman spectroscopy, x-ray diffraction and …

Combustion aerosol technology has distinct advantages for the assembly of chemoresistive
gas sensors compared to their traditional wet chemistry synthesis. These advantages are …

A set of Cr-highly doped TiO2 samples with Cr contents ranging from 5 to 30at.% were
prepared in a sol–gel route and calcined at a temperature between 600 and 900° C. X-ray …
