摘要
多壳层中空金属氧化物具有优异的物理和化学特性。其内部空腔及多壳层结构使其具有大的比表面积,为电化学反应提供了更多的活性位点,因此多壳层中空金属氧化物在电化学领域得到了广泛的应用。本文主要介绍了多壳层中空金属氧化物的合成进展,通过硬模板法、软模板法、选择性刻蚀法和热分解法为例,详细描述了制备得到的不同元素组成、不同壳层数的中空金属氧化物,总结了多壳层中空金属氧化物在超级电容器、锂离子电池和传感器领域表现出的优异性能,最后对多壳层中空金属氧化物的应用前景进行了展望。
The multi-shelled hollow metal oxides have excellent physical and chemical properties.Its internal cavity structure and large specific surface area,provide more active sites for electrochemical reactions,and then it has been widely used in the field of electrochemistry.In this paper,the synthesis progress of multi-shell hollow metal oxides is introduced.The composition of different elements and shell numbers is described in detail by means of hard-template method,soft-template method,selective etching and thermal decomposition.Hollow metal oxides with different number of shell layers are summarized in the field of supercapacitors,lithium-ion batteries and sensors.Finally,the prospects for the application of multi-shell hollow metal oxides are forecasted.
