The synthesis of zeolitic imidazolate framework/prussian blue analogue heterostructure composites and their application in supercapacitors

Abstract

ZIF-67/PBA heterostructure composites was prepared by the ion-exchange method with ZIF-67 nanoparticles as host MOFs. The electrochemical performance of the ZIF-67/PBA heterostructure composites improved after low-temperature calcination.

A general strategy to in situ synthesize hollow metal sulfide/MOF heterostructures for high performance supercapacitors

“…[7][8][9] To address these issues, engineering the architecture and fabricating unique heterostructures have been regarded as useful strategies to boost the electrochemical performance. [10][11][12] On the one hand, the hollow architectures can expose rich active sites, shorten the transfer path of the electrolyte ion and accommodate the volume expansion during electrochemical processes. For instance, Liu et al 13 prepared the hollow structured Ni/Co-MOF by introducing Co 2+ ions as structure-directing agents, exhibiting high capacitance, excellent rate capability and good cycling stability.…”

“…ZIFs, comprising metal ions and imidazolate linkers, exhibit high surface areas and controlled topologies. 15 PBAs are cyanide-bridged coordination polymers with three-dimensional open frameworks and adjustable compositions and exhibit high thermal and cycling stability. 16 The integration of ZIFs and PBAs is a promising strategy to enhance electrochemical performance.…”

“…Coordination polymers (CPs) are versatile precursors used to fabricate porous materials with large surface areas and flexible compositions. , As the typical subfamilies of CPs, metal–organic frameworks (MOFs) (including zeolitic imidazolate frameworks (ZIFs)) and Prussian blue analogs (PBAs) are widely utilized as precursor templates to explore structure–property relationships. ZIFs, comprising metal ions and imidazolate linkers, exhibit high surface areas and controlled topologies . PBAs are cyanide-bridged coordination polymers with three-dimensional open frameworks and adjustable compositions and exhibit high thermal and cycling stability .…”

Preparation, characterization, and electrochemical sensing performance of a novel pristine Cd-MOF and its composite with carbon nanotubes

“…MOFs provide an infinite array of metal ion centers and connecting ligands, which may be redox active or inactive. The research progress in the field of redox active MOFs shows that they may act as the ideal platform for the development of efficient electrochemical devices such as supercapacitors, [19][20][21][22][23][24] ion storage systems, 25,26 and electrochemical sensors. [27][28][29][30][31][32][33][34][35] Among them, low dimensional 2D MOFs have attracted more and more attention due to their exposed functional groups and open interfaces.…”
