板钛矿

Brookite TiO〓 particles have no absorption within the UV-Vis band, they can not be used as photocatalyst.

板钛矿型二氧化钛在整个紫外可见区域没有吸收，因而不可能作为光催化剂使用。

Dopant Sb enhances the crystallization rate of the TiO2 from amorphous to brookite and anatase phase.

掺杂Sb提高了TiO2由无定型向板钛矿和锐钛矿转变的速率。

Its crystal type have anatase, brookite and rutile.

晶型有锐钛矿型、板钛矿型和金红石型。

It is found that anatase is easier to form at acidic condition, but rutile and brookite at basic condition, using methanol as solvent.
