Abstract:
  Thanks to their distinguished properties such as optimized specific surface area, low density, high loading capacity and sequential matter transfer and storage, hollow multi-shelled structures (HoMSs) have caused great interest of scientists in broad fields, including catalysis, drug delivery, solar cells, supercapacitors, lithium ion batteries, electromagnetic wave absorption and sensors. However, traditional synthesis methods such as soft-templating and hierarchical self-assembly methods can hardly realize the controllable synthesis of HoMSs, thus limiting their development and application. In this current report, we first succinctly review the development process of HoMSs and conclude the shortcomings of traditional synthesis method. Subsequently, we introduce a sequential templating approach which shows great generality for the synthesis of HoMSs with controllable composition and geometry configuration and exhibits remarkable effect on the scientific research field. We then deeply explore the basic material science and chemical reaction mechanism involved in the synthesis and manipulation of HoMSs using our sequential templating approach. In addition, we highlight the effect of the geometric characteristics of HoMSs on their application properties. Finally, the current challenges and future research directions of HoMSs are also suggested.
