摘要/Abstract

摘要： 以TiCl₄为钛源,利用微波加热在0.1~4.0MPa压力条件下制备了纳米TiO₂粉末,研究了不同反应压力对TiO₂物相成分,晶体结构及光催化活性的影
响.结果表明:反应压力对纳米TiO₂的晶相结构、微观形貌及光催化性能有较大的影响.在相对较低反应压力时,纳米TiO₂产物以锐钛矿相为主,并
有少量的板钛矿相存在,当压力达到4.0MPa时有大量的金红石相出现.TEM测试显示TiO₂粉末的粒径在5~30nm范围内,且随着压力增大,晶粒尺寸增
大,结晶性能增强.随制备压力的增大,TiO₂粉末的光催化效率先升高而后单调性地降低,2.0MPa压力时光催化效率达到最高.

Abstract: Nanocrystalline TiO₂ powders were synthesized from TiCl₄ solution by the highpressure microwave method under pressure ranging from 0.1MPa to 4.0MPa. The phase structures, microstructures and photocatalytic properties of the nanocrystalline
TiO2 were investigated. It was found that the reaction pressure had a large impact on the phase structures, microstructures,
and photocatalytic properties of the nanocrystalline TiO₂. Under lower reaction pressure, TiO2 products consisted of anatase
and brookite phase, with the brookite phase in minority, while under higher reaction pressure, a large quantity of rutile
TiO₂ was formed. With the increase of reaction pressure from 0.1MPa to 4.0MPa, the average sizes of the TiO₂ nanoparticles
increased from 5nm to 30nm. At reaction pressures lower than 2.0MPa, the photocatalytic performance of the nanocrystalline
TiO₂ increased with the pressure, while at pressures higher than 2.0MPa, the photocatalytic performance was found to decrease
monotonically with the pressure.

Key words: high-pressure microwave synthesis, nanocrystalline TiO₂, photocatalysis
