DFT study of TiO2 brookite (210) surface doped with silver and molybdenum
Materials Research Express, 2022 The most popular semiconductor in dye-sensitized solar cells (DSSCs) is titanium dioxide (TiO _2 ) because of its low cost, non-toxicity, and good stability.

Synthesis of Pure Brookite Nanorods in a Nonaqueous Growth Environment
Crystals, 2019 Brookite TiO2 is the most difficult TiO2 polymorph to synthesize. The available methods in the literature to produce brookite nanostructures mostly use water-based techniques for the preparation of water-soluble Ti complexes first, followed by a ...

Effect of PEG on rheology and stability of nanocrystalline titania hydrosols [PDF]
, 2009 Very stable titania hydrosols were prepared by fast hydrolysis of titanium isopropoxide in a large excess of water. XRD patterns show that these sols contain nanocrystals (5–6 nm) of anatase (70%) and brookite (30%).

Brookite: Nothing New under the Sun? [PDF]
Catalysts, 2017 Advances in the synthesis of pure brookite and brookite-based TiO2 materials have opened the way to fundamental and applicative studies of the once least known TiO2 polymorph. Brookite is now recognized as an active phase, in some cases showing enhanced performance with respect to anatase, rutile or their mixture.
