Brookite, a sometimes under evaluated TiO ₂ polymorph

RSC Advances, 2022
Brookite positively affects solar photocatalysis, electrocatalysis and electrochemical applications by stabilizing photogenerated e − /h + pairs. Brookite-related heterojunctions, cus Ti atoms, surface acidity and redox behaviour are crucial aspects.

Sol-Gel Processes in Micro-Environments of Black Shale: Learning from the Industrial Production of Nanometer-Sized TiO2 Polymorphs

ChemEngineering, 2019
Micro-environments in black shale are reactors for geochemical reactions that differ from the bulk scale. They occur in small isolated pores of several 10 s to 100 s of nanometers without or with limited ionic exchange by diffusion to the surrounding ...
