High-Pressure Study of Anatase TiO2 [PDF]

Materials, 2010
We report resistivity and thermo-electric power measurements of the anatase phase of TiO2under pressure up to 2.3 GPa. Despite its transparent appearance, the single crystal of anatase exhibits a metallic-like resistivity above 60 K, at all pressures.

A roadmap of strain in doped anatase TiO2 [PDF]

Scientific Reports, 2018
AbstractAnatase titanium oxide is important for its high chemical stability and photocatalytic properties, however, the latter are plagued by its large band gap that limits its activity to only a small percentage of the solar spectrum. In that respect, straining the material can reduce its band gap increasing the photocatalytic activity of titanium ...

TiO₂ sintetizado por el método de precursor polimerico (Pechini): estructura de la resina intermedia

Boletín de la Sociedad Española de Cerámica y Vidrio, 2011
In this work, the polymeric precursor method (Pechini method) was used to synthesize titanium dioxide. This process allowed a bigger control on the purity of the oxide and the crystalline phase present in the material.

Improved Adsorption and Photocatalytic Degradation of Methyl Orange by Onion-like Nanocarbon/TiO₂ Nanocomposites

Applied Sciences, 2023
Waste cooking oil, a known environmental pollutant, has been used as a precursor for the synthesis of onion-like nanocarbons (OLNCs) using flame pyrolysis. The OLNCs were added to TiO2 to form TiO2/OLNC nanocomposites through hydrothermal treatment.
