摘　　要：中空结构材料密度低、比表面积大、具有较高的容载能力,在环境保护、生物医药、能量存储等领域具有广泛的应用。牺牲模板法由于模板本身作为反应物参与壳材料的构造过程,不需要进行模板修饰及模板去除工作,被广泛用于制备中空微纳米结构材料。综述了近年来利用化学刻蚀、离子交换、电化学置换和金属盐分解等牺牲模板法制备中空材料的研究进展。Hollow nanostructures with lower density,higher surface area,higher capacity and other better properties than solid materials have attracted tremendous attention because of the great potentials in many areas such as environmental protection,biomedicine and energy storage. Sacrificial templating method has been frequently employed to fabricate hollow structural materials because the templates are involved in the process of the formation of the shell as a reactant without any modification. In this review,an overview of the preparation of hollow structural materials via sacrificial templating methods,including chemical etching,ion exchange,galvanic replacement and metal salt decomposition,is provided.
