二氧化钛基核/壳复合材料的研究进展

Research Progress in Titania-based Composites with Core/Shell Structures

由于具有优异的光催化性能,二氧化钛在光电转换、光催化等新兴领域获得了大量的应用。而以二氧化钛为核的核/壳结构复合材料,由于可以产生不同于其本身和壳体材料的独特的全新性能,近年来受到了越来越多的关注。根据壳体材料的不同,从制备方法、表征和物性研究等方面分别介绍了以单质、聚合物、无机氧化物和杂化材料为壳的二氧化钛基核/壳结构复合材料的研究进展。最后展望了二氧化钛基核/壳结构复合材料的发展前景。

TiO2 has wide application in photocatalytic, photoelectric conversion and other new fields due to its excellent photocatalytic properties. But titania-based composites with core/shell structures have received more and more attention because of they can produce some special and new properties which is different from core and shell recently. According to the difference of shell materials, research progress in titania-based composites with core/shell structures from preparation methond, character, physical research, the composites including simple substance, polymer, inorganic oxides and hybrid materials as shell is introduced. At last, the development prospects of the titania-based composites with core/shell structures are proposed.
