Abstract

Back cover image: Hollow structure materials usually exhibit good performance in the field of electrochemistry because of their large specific surface area and abundant active sites. Prussian blue and its analogs (PB/PBAs) usually contain two or more kinds of transition metal elements, and the synergistic effect between different metal elements often improves the performance. Hollow structure PB/PBAs can be synthesized by adjusting the synthesis strategy. Moreover, a variety of hollow structure derived materials can be obtained via easy derivative treatment for PB/PBAs. These derivatives can alleviate the poor conductivity of PB/PBAs, thus exhibiting better electrochemical performance. In article number CNL264, the synthesis strategies of hollow PB/PBAs and their derived materials are systematically summarized, the applications of related materials in the field of electrochemistry are introduced in detail, and the prospects and challenges are further analyzed.
