title: Synthesis of Monocrystalline Nanoframes of Prussian Blue Analogues by Controlled Preferential Etching.
abstract: Metal cyanide coordination compounds are recognized as promising candidates for broad applications because of their tailorable and adjustable frameworks. Developing the nanostructure of a coordination compound may be an effective way to enhance the performance of that material in application-based roles. A controllable preferential etching method is described for synthesis of monocrystalline Prussian blue analogue (PBA) nanoframes, without the use of organic additives. The PBA nanoframes show remarkable rate performance and cycling stability for sodium/lithium ion insertion/extraction.
