La3+’s Effect on the Surface (101) of Anatase for Methylene Blue Dye Removal, a DFT Study
Molecules, 2022 Density functional theory (DFT) is a widely used method for studying matter at the quantum level. In this study, the surface (101) of TiO2 (anatase phase) was considered to develop DFT calculations and explain the effect of lanthanum ion (La3+) on the ...

Anatase TiO2 adsorption on 3-aminopropyltrimethoxysilane-modified Al or glass surfaces
Heliyon, 2019 Herein, anatase titanium dioxide (TiO2) nanoparticles were prepared by boiling anatase TiO2 in water without using hydrothermal synthesis. This changed the particle diameter because boiling caused particle collision via convection.

Rutile-anatase Composite Catalyst Formed by Coupling Anatase and Rutile Particles [PDF]
Chemical and Materials Engineering, 2013 Anatase-type TiO2 particles were formed on a surface of rutile particles by thermal crystallization from amorphous titan oxyhydroxide that was obtained from the aqueous solution of TiOCl2 using urea hydrolysis. Special attention was paid to obtain rutile-anatase composite with reproductive physico-chemical properties by control of synthesis parameters.

Sulphuric Acid Digestion of Anatase Concentrate
Mining, 2023 The processing of anatase ores by sulphuric acid digestion is well known for its low titanium dissolution yields, which makes the process economically and technically unfeasible. Anatase is considered much less reactive than other forms of titanium such as ilmenite and rutile. Generally, to enhance its dissolution, thermal processes along with acid and/
