MOF derived ZnO/C@(Ni,Co)Se2 core–shell nanostructure on carbon cloth for high-performance supercapacitors

A high-performance hybrid supercapacitor by encapsulating binder-less FeCoSe2 nanosheets@NiCoSe2 nanoflowers in a graphene network

“…The redox reactions related to the FCS@NCS2@NF electrode could be related to the following equations. 75,76 FeCoSe 2 + 2OH − ↔ FeSeOH + CoSeOH + 2e − FeSeOH + OH − ↔ FeSeO + H 2 O + e − CoSeOH + OH − ↔ CoSeO + H 2 O + e − NiCoSe 2 + 2OH − ↔ NiSeOH + CoSeOH + 2e − NiSeOH + OH − ↔ NiSeO + H 2 O + e − CoSeOH + OH − ↔ CoSeO + H 2 O + e − …”

Metal–Organic Framework Materials for Electrochemical Supercapacitors

“…Supercapacitors based on transition metal oxides store energy mainly through Faraday charge transfer generated by redox reaction during charging and discharging [140,141]. The Faraday pseudocapacitance of metal oxide can occur not only at the interface between the electrode and the solution but also in the inner part of the electrode itself, which greatly improves the utilization rate of the material, so the metal oxide material has a larger specific capacitance.…”

A high‐performance hybrid supercapacitor electrode based on ZnO/nitrogen‐doped carbon nanohybrid

“…[45] ZnO nanoparticles showed the highest capacitance. The electrochemical performance of ZnO can be improved via conjugation with other metal oxides such as MnO x , [46] NiO/graphene oxide (GO), [47] CeO 2 , [48] (Ni, Co)Se 2 , [50] Co 3 O 4 , [51] cellulose nanofibers, [52] and ZIF-8.
