The mesoporous titania with TiO2(B) (mt-TiO2(B)), which has a lattice-matched core-shell crystalline structure with a thin TiO2(B) phase sheathing an anatase core, was synthesized from potassium titanate (K2Ti2O5) by hydration, ion exchange, and calcination. TiO2(B) is a crystalline form of titania with a looser structure than anatase and rutile. Its synthesis, structure, and functions are reviewed. It has all the features of a large specific surface area with a mesoporous architecture, pore wall of high crystallinity and high thermostability. Nanoparticles of noble metals in this mesoporous structured titania are stable. Its potential industrial applications include photocatalysis, oil hydrorefining, and use as a drug carrier, solid acid catalyst, and electrode material. A pilot plant to prepare this unique multifunctional titania material at low cost has been established with a production capacity of 20 tons per year.

TiO2(B)介孔二氧化钛的合成、特性及应用

介孔二氧化钛与 TiO2(B) (mt-TiO2(B)) 具有晶格匹配的核壳晶体结构,薄的 TiO2(B) 相包裹着锐钛矿核,是由钛酸钾 (K2Ti2O5) 合成的水化、离子交换和煅烧。TiO2(B) 是二氧化钛的结晶形式,其结构比锐钛矿和金红石更松散。综述了其合成、结构和功能。它具有大比表面积、介孔结构、高结晶度和高热稳定性的孔壁的所有特征。这种介孔结构的二氧化钛中的贵金属纳米颗粒是稳定的。其潜在的工业应用包括光催化、石油加氢精制以及用作药物载体、固体酸催化剂和电极材料。
