Unusual energy storage and charge retention in Co-based metal–organic-frameworks

Facile synthesis of novel metal-organic nickel hydroxide nanorods for high performance supercapacitor

“…For example, Lee et al reported that Co-based MOF film that using terephtalic acid as organic linker exhibited a specific capacitance of 206.8 F g -1 at a current density of 0.6 A g -1 [11], and longer organic linker could induce higher specific capacitances [12].…”

“…However, only layered leaflet like MOF materials have been utilized as electrode materials for supercapacitors [11][12][13][14][15][16], and new MOF materials with unique 1D nanostructures need to be further designed. In this paper, 1D Ni-based MOF nanorods with uniform morphology were successfully synthesized under mild conditions using salicylic acid as new organic linker and used as supercapacitor electrodes for the first time.…”

Recent advancements in metal organic framework based electrodes for supercapacitors

“…Lee et al [45] synthesised Co-based MOFs at 100°C using cobalt nitrate and terephtalic acid for supercapacitors. A Co-MOF film with a uniform thickness of 5 μm was constructed by MOF nanoparticles ranging from 50 to 100 nm (Fig.…”

“…Typically, three organic linkers, 1,4-benzenedicarboxylic acid (H 2 BDC), 2,6-naphthalenedicarboxylc (H 2 NPC) and 4,4-biphenyldicarboxylic (H 2 BPDC) with increased molecular lengths were used. These Co-MOF films were produced using blade coating technique as previously employed by Lee et al [45]. They found that a longer organic linker produced larger pores and larger surface area, compared with a shorter linker.…”

“…The Co-MOF has a biggest capacitance of 154.5 F g -1 using the LiOH electrolyte with a concentration of 1 M [46].…”
