Synthesis of Prussian Blue Nanopartieles with a Hollow Interior by Controlled Chemical Etching

摘要

Hollow particles, an important class of materials with large internal cavities and thin shells, present a wide range of potential applications, such as energy storage, chemical calalysis, photonics, and biomedical carriers. The properties of hollow particles are strongly affected by the compositions and exquisite nanostructures of the shell regions. Many efforts have been made to control these parameters. Recently, hollow particles with nanoporous shells have attracted great interest because the large pore volumes and high surface areas provided by the nanoporous shells show large storage capacity and allow guest species to pass easily into the internal cavity. For instance, metal oxide hollow particles present a superior lithium storage capacity and good cycle performance, which could improve gas sensitivity and catalytic performance in other applications.
