Brookite versus anatase TiO2 photocatalysts: Phase transformations and photocatalytic activities [PDF]
Titanium dioxide nanoparticles consisting of pure anatase, anatase-rich, brookite-rich, and pure brookite modifications were synthesized and characterized by X-ray diffraction, field emission-scanning electron microscopy and nitrogen adsorption.

Catalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application [PDF]
Catalyst layers (4–20 lm) of rhodium (1 wt%) supported on alumina, titania, and ceria–zirconia (Ce0.5Zr0.5O2) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water.

Hydrogen-doped Brookite TiO2 Nanobullets Array as a Novel Photoanode for Efficient Solar Water Splitting [PDF]
As a representative photocatalyst for photoelectrochemical solar water splitting, TiO2 has been intensively studied but most researches have focused on the rutile and anatsase phases because brookite, another important crystalline polymorph of TiO2 ...

First-Principles Investigation of Ru- and Pt-Doped TiO2 Brookite Surfaces
The electronic structures and optical properties of brookite TiO2 (100) and (110) surfaces doped with transition metals (Ru and Pt) have been investigated by first-principles calculations based on the density functional theory, employing generalized ...
