Hexacyanometallates, known as Prussian blue (PB) and its analogues (PBAs), are coordination compounds with a regular and porous open structure. PBAs can be used as templates to prepare hollow and highly porous nanostructures of various compositions. This review examines the synthesis and properties of derivatives derived from PBAs. Challenges in manipulating the derivatives' properties are discussed, and synthetic approaches for target applications are presented.
Hexacyanometallates, known as Prussian blue (PB) and its analogues (PBAs), are a class of coordination compounds with a regular and porous open structure. The PBAs are formed by the self-assembly of metallic species and cyanide groups. A uniform distribution of each element makes the PBAs robust templates to prepare hollow and highly porous (hetero)nanostructures of metal oxides, sulfides, carbides, nitrides, phosphides, and (N-doped) carbon, among other compositions. In this review, we examine methods to derive materials from PBAs focusing on the correlation between synthesis steps and derivative morphologies and composition. Insights into catalytic and electrochemical properties resulting from different derivatization strategies are also presented. We discuss challenges in manipulating the derivatives' properties, give perspectives of synthetic approaches for the target applications and present an outlook on less investigated grounds in Prussian blue derivatives.
