摘　　要：过渡金属化合物多壳空心球密度低、比表面积大,同时具有较高的光俘获效率,相对于传统的简单中空结构材料在应用中具有更显著的优势,其形状、大小、组成和壳层数可控的中空结构具有独特的性能优势。本文主要介绍了过渡金属化合物多壳空心球的不同制备方法,如硬模板法、软模板法和无模板法;概述了不同反应条件对过渡金属化合物形貌的影响;总结了其应用在锂电池、染料敏化太阳能电池、超级电容器和传感器等领域时表现出的优异性能;并对过渡金属化合物多壳空心球的可控合成进行了前景展望。Transition-metal compound multiple-shell hollow spheres show significant material advantages in many applications over conventional simple hollow structures due to their low density, high surface area,as well as high light-harvesting efficiency. They have unique structural features and intriguing properties,hollow structures with tunable size,shape,composition and interior architecture. The vast array of synthetic strategies used to create multi-shelled hollow structures,such as hard templates,soft templates and free templates methods,were summarized. With rising interest in engineering in the morphology of transition-metal compounds multiple-shell hollow spheres during the past decade,it is found that their performance is also deeply affected by their morphology characteristics. Furthermore,the possible application of these novel materials for lithium ion battery, dye-sensitized solar cells,supercapacitor and gases sensing,were discussed. The future developments of synthetic strategies about multi-shelled hollow structures were also prospected.
