Hydrothermal Synthesis of Brookite

Chemistry Letters, 1999
Abstract Hydrothermal synthesis of brookite was performed at 110-200 °C within 24 h using amorphous TiO2 and sodium salts as the starting material. Brookite was obtained as an almost single phase at 200 °C and TiO2 / NaOH mole ratio ≅ 1.

Photoactivity of brookite–rutile TiO2 nanocrystalline mixtures obtained by heat treatment of hydrothermally prepared brookite

Materials Chemistry and Physics, 2011
Abstract Pure brookite phase was prepared by hydrothermal synthesis of titanium peroxo-complex in the presence of glycolic acid at 220 °C. The structure of prepared brookite samples was determined by X-ray powder diffraction (XRD) and selected area electron diffraction (SAED).

Sol–gel synthesis of mesoporous anatase–brookite and anatase–brookite–rutile TiO2 nanoparticles and their photocatalytic properties

Journal of Colloid and Interface Science, 2015
TiO2 photocatalysts with a mixture of different TiO2 crystal polymorphs have customarily been synthesized hydrothermally at high temperatures using complicated and expensive equipment. In this study TiO2 nanoparticles with a mixture of TiO2 crystals were synthesized using a modified sol-gel method at low temperature. In order to form nanoparticles with

Preparation of photocatalytic brookite thin films

Thin Solid Films, 2007
Pure brookite films were deposited from a brookite dispersion obtained by peptizing a mixture brookite–rutile prepared by thermolysis of TiCl4 in a HCl solution. The films were characterised by X-ray diffraction and Raman spectroscopy. The photoactivity of the samples was tested by using the photo-oxidation of 2-propanol in gas–solid regime as a probe ...

Studies on the brookite-rutile transformation

Transactions of the Faraday Society, 1961
Brookite, the orthorhombic modification of titanium dioxide, transforms to the tetragonal modification, rutile, on heating. The kinetics and energetics of the transformation have been studied. Below 715±10°C, the rate of transformation is extremely slow. There appears to be little or no induction time.

A novel multilayer brookite TiO2 electrode for improved performance of pure brookite-based dye sensitized solar cells

Chemical Physics Letters, 2020
Abstract A novel multilayer brookite TiO2 film-based dye-sensitized solar cell (DSSCs) is proposed and prepared by three kinds of brookite TiO2 nanoparticles. By optimizing the structure of multilayer brookite TiO2 electrode, the optimal photovoltaic conversion efficiency of multilayer brookite-based solar cell could reach to 8.16%, which is much ...

Spinel lithium titanate from brookite nanocrystallites

Ceramics International, 2014
Abstract Spinel lithium titanate nanoparticles have been synthesized using anatase and brookite nanocrystallites, as precursors. The corresponding products, A- and B-Li 4 Ti 5 O 12 nanoparticles, have distinct differences in the optical absorption property, electrochemical performance and photocatalytic activity.
