Hierarchical ZnO arrays engineered hollow carbon nanofibers derived from metal-organic frameworks for flexible supercapacitors

Nanotechnology in Advanced 2D and 3D Nanostructured Transition Metal Oxide Based Flexible Supercapacitors: A Review

“…[118] However, ZnO's weak electrical conductivity and rigid properties restrict its use in FSC systems. Numerous ZnO-based composites have been fabricated to address these problems such as incorporating rGO in to ZnO such as rGO/ZnO nanorods/rGO, [188] ZnO/rGO/ZnO, [189] polyvinylidene fluoride-ZnO-rGO, [190] NCNF@rGO-@ZnO, [191] ZnO/CNT [192] and combination with other TMO such as CuO (ZnO/CuO/rGO) [193] improved the specific capacity of ZnO which indicates that the composites of ZnO is promising to be applied in a FSC. Fe 3 O 4 has been electrochemically studied as an essential electrode material for FSCs due to its low cost, availability, low environmental impact, high theoretical specific capacitance (2299 F/g), large potential window, and multiple valence states.…”

Functions and applications of emerging metal–organic-framework liquids and glasses

“…As a large family of coordination polymers (CPs), metal-organic frameworks (MOFs) with more than 70 000 structures are known as porous crystals composed of metal nodes (clusters or ions) and organic bridging ligands linked via coordination bonds. [1][2][3] The arrangement of moieties within the crystalline framework is well organized to form long-range ordered and infinite networks. [4][5][6] Owing to the modifiable organic and inorganic building units, MOFs with tunable physicochemical properties show a variety of noticeable electrical, optical, and magnetic behaviors, which provide great potential for future applications such as gas sorption and separation, proton conduction, catalysis, drug delivery, etc.…”

Sulphur vacancy induced Co3S4@CoMo2S4 nanocomposites as a functional electrode for high performance supercapacitors

“…10,11 These properties confer great advantages for MOFs as advanced potential electrode materials for energy storage and conversion devices such as batteries, supercapacitors and fuel cells. [10][11][12][13][14] However, the biggest hurdle facing the application of MOFs as supercapacitors is possession of relatively low conductivity and reduced ability for ion transport within the electrolyte, thereby hindering their application in energy storage and conversion. This problem can be addressed by applying MOFs as sacricial template agents to generate porous carbon networks with metals or metal oxides that enhance the conductivity and electrochemical reactivity.…”
