Facile synthesis of brookite TiO2 nanoparticles

Abstract

Brookite is the most difficult TiO₂ polymorph to obtain in phase pure form. Here we report on a facile synthesis method for phase-pure brookite nanoparticles using a broad range of titanium precursors. General availability of phase pure brookite opens up multiple research activities to explore both fundamental properties as well as applications. The synthesis method is scalable and thus it potentially allows for large-scale industrial production.
