Heterophase Polymorph of TiO2 (Anatase, Rutile, Brookite, TiO2 (B)) for Efficient Photocatalyst: Fabrication and Activity [PDF]

open access: goldNanomaterials, 2023
TiO2 exists naturally in three crystalline forms: Anatase, rutile, brookite, and TiO2 (B). These polymorphs exhibit different properties and consequently different photocatalytic performances.

High-fraction brookite films from amorphous precursors [PDF]

open access: greenScientific Reports, 2017
AbstractStructure-specific synthesis processes are of key importance to the growth of polymorphic functional compounds such as TiO2, where material properties strongly depend on structure as well as chemistry. The robust growth of the brookite polymorph of TiO2, a promising photocatalyst, has been difficult in both powder and thin-film forms due to the

Unveiling the synergistic role of anatase/brookite homojunctions in TiO2 mixed phases on the enhanced photocatalytic degradation of paracetamol under simulated solar light and the formation of CO2.− radical ion

open access: greenApplied Surface Science Advances
Mixed-phase TiO₂ systems offer unique opportunities for enhancing photocatalytic performance via interpolymorph junctions (homojunctions). While anatase/rutile interfaces have been extensively studied, anatase/brookite junctions remain comparatively ...
