Anatase TiO2 nanocrystals with hexagonal prism and hollow microstructures were synthesized by heating titanium oxide oxalate hydroxide hydrate microstructures obtained by refluxing at 90 ℃ using tetrabutyl titanate [Ti(OC4H9)4] as a precursor.
无气泡持续产生时,得到六棱柱结构锐钛矿相TiO2;有气泡持续产生时,以气泡为模板,得到空壳结构锐钛矿相TiO2。
