Brookite, a sometimes under evaluated TiO2 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.

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%).
