Synthesis of zeolitic imidazolate framework-67 nanocube wrapped by graphene oxide and its application for supercapacitors

Metal–Organic Frameworks Constructed from Iron‐Series Elements for Supercapacitors

“…Similar carbon-compositing work can also be seen in recent reports, and they also achieved sound synergy effects on the electrochemical properties. [170][171][172] Except for pristine carbon materials, MXenes (a type of 2D conductive materials) were also documented as the matrix to composite with MOF-based active materials. [173,174] For instance, Ti 3 C 2 T x /Ni-MOFs compositing electrode, synthesized by the Zhang group, [174] displayed an excellent electrochemical property with 1124 F g À1 at a current-density value of 1 A g À1 and 62% of rate capability even at an ultrahigh current density of 20 A g À1 .…”

Supercapacitor electrodes based on metal‐organic compounds from the first transition metal series

“…For SCs based on monometallic organic compounds, cobalt is the most commonly used metal in the first transition metal series 25,27,50,67,69,72,73,97‐134 . Summarized in Tables 3 and 4 are the electrode and SC performances of cobalt‐organic compounds and their composites ( 12 ‐ 92 ).…”

“…They are ideal for the storage of charges in the electrical double layer due to their intrinsically high surface area and the combination of the advantages of MOFs with high stability and framework diversity 69,117 . ZIF‐67, a Co‐MOF with the linker of 3‐methylimidazolate (mIM), and its composites ( 56 ‐ 78 ) have gained an increasing attention in recent years for the application in SCs 69,117‐128 . In 2016, Worrall and coworkers reported the pristine ZIF‐67 ( 56 ) with a high surface area of 1521 m 2 g −1 as electrode materials for SC application, 117 which has exceeded the surface areas for other Co‐polycarboxylate MOFs from 1.81 to 1192.9 m 2 g −1 .…”

An overview of supercapacitors electrode materials based on metal organic frameworks and future perspectives

“…The reason for good electrochemical response of ZIF-67/GO-n composite credited to huge surface area of ZIF-67 nanocubes combined with conductive nature of GO. 139 Du et al in 2020, develop a conducting anionic cage of Co-MOF accompanied with zeolite framework developed on the Ni foam and utilized as an anode for supercapacitors without any conductive material. The final electrodes parade superior electrochemical activity in terms of good rate capability and capacitance of 236.2 F/g at 1A/g.…”
