【摘要】 本文从制备方法、微观结构、光催化活性研究等方面介绍了本课题组近几年从事的具有纳米结构的氧化钛、被修饰在介孔材料中的氧化钛以及沉积了贵金属的纳米结构氧化钛的研究成果 ,并总结了纳米氧化钛的结构特点和对应的光催化性质的规律。纳米氧化钛因颗粒尺寸下降而具有与微米氧化钛不同的特殊性质 ,有着广泛的应用前景 ,是具有光催化性质的氧化钛的研究热点。更多还原

【Abstract】 The research and development of nanostructured titania and the titania modified on MCM-41 with or without Pt deposition in our group were reviewed on the preparation,structure and photocatalytic properties in this paper.The structure characters of nanosized titania and the corresponding photoactivities were discussed.The development of the photocatalytic titania has generated interest due to special properties of nanosized tiania,which differs from those of micro titania,and their potential applications.更多还原
