综述了近年来本课题组依据材料化学工程研究思想,对含TiO2(B)(一种比金红石和锐钛矿相结构更松散的氧化钛晶型)介孔氧化钛材料在制备、结构和性能方面所取得的研究进展.该介孔材料由二钛酸钾经水合、离子交换和热处理得到,具有良好原子尺度晶格匹配界面特征的锐钛矿和TiO2(B)核壳结构.研究表明,该介孔材料在兼备高比表面积、高晶化孔壁和高热稳定性的同时,还表现出良好的纳米颗粒担载稳定性,在光催化、油品加氢精制、药物载体、固体酸催化和电化学电容器等方面已凸显出良好的应用潜力和推广价值.目前该新型含TiO2(B)介孔氧化钛材料已经实现低成本、规模化制备.
In this paper, based on the research thought of material chemical engineering in recent years, the preparation and structure of mesoporous titania materials containing TiO2 (B), which is more loose than rutile and anatase phase, Properties of the mesoporous material anatase and TiO2 (B) core-shell structure obtained by hydration, ion exchange and heat treatment of potassium titanate with a good atomic scale lattice matching interface characteristics have been studied , The mesoporous material also has good nanoparticle loading stability while having high specific surface area, high crystallized pore wall and high thermal stability. In the photocatalytic, oil hydrotreating, pharmaceutical carrier, solid acid Catalytic and electrochemical capacitors and other aspects have highlighted the potential for good and promotional value.This new TiO2 (B) mesoporous titania materials have been achieved low-cost, large-scale preparation.
