Effect of C doping on the structural and optical properties of sol–gel TiO2 thin films

Controllable preparation of TiO2 nanowire arrays on titanium mesh for flexible dye-sensitized solar cells

“…However, the preparing conditions of the anodic oxidation are demanding, and the morphology of the TNT arrays cannot be easily controlled; furthermore, the prepared TNT arrays would be inclined to fall off from the substrate. Up to now, various techniques have been designed to synthesize TiO 2 nanostructures including anodic oxidation [18], sol-gel [19], hydrothermal [20], chemical vapor deposition (CVD) [21], microwave [22], and electrodeposition methods [23].

A Simple Route in Fabricating Carbon-Modified Titania Films with Glucose and Their Visible-Light-Responsive Photocatalytic Activity

“…Hence, the number of studies on how to immobilize catalysts on glass substrates and extend the photocatalytic activity of TiO 2 beyond ultraviolet light has extensively risen in recent years. Carbon-modified TiO 2 photocatalysts not only show improvement in photocatalytic activity, but also influence TiO 2 's natural properties, including crystallinity, specific surface area, characteristic temperatures, and the recombination rate of e − /h + pairs [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Sampaio et al tried to mix sol-gel TiO 2 powders with carbon nanotubes (CNTs) by using hydration-dehydration technology [7].…”

“…TiO 2 films were prepared via various technologies, such as sol-gel, chemical vapor deposition, physical vapor deposition, spray pyrolysis, spin-coating, and impregnation processes [8][9][10][11][12]. For practicality and cost-effective considerations, the most acceptable product is synthesized through a simple process and common materials.…”

Influence of C substitution on the oxygen sites of TiO2 (001) surface

“…Some studies [9] suggest that the (001) surface of TiO 2 has photo catalytically more reactive than the majority (101) surfaces. Some experiment and calculations has studied the effects of C substitution on the TiO 2 [17][18][19], but the study of C substitution on TiO 2 surface is rare, it is important to know the influence of C atom substitution on the TiO 2 surface. In this paper, the studying surface was the bulk anatase TiO 2 (001) surface, twofold coordinated O atom (O 2c ) and threefold coordinated O atom (O 3c ) were substituted for C atom, respectively.…”
