Supercapacitive property of metal–organic-frameworks with different pore dimensions and morphology

Recent advancements in metal organic framework based electrodes for supercapacitors

“…It was found that the porous carbon prepared with H 3 BDC displayed the highest de-gree of graphitization. In contrast to the results of Lee et al [48], the porous carbon materials showed higher SSA as the length of the organic ligand chain, or "strut" length, decreased. Hence, the highest SSA of 2,816 m 2 g −1 was measured for the porous carbon material using H 2 BDC.…”

“…Following the above report, Lee et al [48] further studied the effects of organic linkers with different molecular lengths on producing Co-MOFs with different pore sizes and surface areas (Fig. 2a-c).…”

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

“…186.8 m 2 g -1 calculated from the desorption line, which is higher than most reported MOF nanomatrials [8,12,15,28,29]. The high surface area helps to improve the contact area between electro active materials and electrolyte ions, and thus the specific capacitance can be substantially increased.…”

“…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.…”
