我们报道了一种大规模的自腐蚀方法来合成单分散的介孔F-TiO(2)中空微球。从固体微球到空心微球的形貌、化学组成和尺寸随H(2)SO(4)浓度的增加而变化的情况，阐明了HF的自刻蚀过程。制得的二氧化钛空心微球易于膜过滤和光催化同时进行，在深度水处理中具有很高的工程应用潜力，不仅可以提高水的产量，还可以改善水质。
We report a large-scale self-etching approach for the synthesis of monodispersed mesoporous F-TiO(2) hollow microspheres. The self-etching derived from HF was elucidated by the morphology, chemical composition, and crystal size evolutions from solid to hollow microspheres with the increase in the concentration of H(2)SO(4). The resulting TiO(2) hollow microspheres exhibited ease for the concurrent membrane filtration and photocatalysis, providing high potential for engineering application in advanced water treatment, for not only increasing water production but also improving water quality.
