A Polythreaded Mn-Ii-Mof And Its Super-Performances For Dye Adsorption And Supercapacitors
INORGANIC CHEMISTRY FRONTIERS(2020)
Abstract
A new polythreaded Mn-II-MOF based on a tridentate N-containing ligand was synthesized via a hydrothermal method, namely, [Mn-2(Tipa)(2)(1,4-bdc)(2)(H2O)(2)]center dot 3H(2)O (MnTB), where Tipa and 1,4-bdc are short for tri(4-imidazolylphenyl)amine and 1,4-benzenedicarboxylate. MnTB possesses a fascinating 2D -> 2D polyrotaxane layer with a (4(2)center dot 6)(4(2)center dot 6(3)center dot 8) topology, and these layers are extended into a 3D polythreaded framework with a polythreaded character. The crystal was pulverized and directly used as both a dye adsorbent and supercapacitor. In the adsorption test, MnTB showed great adsorption ability for methyl orange (MO), where the maximum adsorption capacity was about 1500 mg g(-1). When tested as a supercapacitor, MnTB exhibited a high capacitance of 1357.8 F g(-1) at 1 A g(-1) in 6 M KOH solution and achieved no attenuation after 2000 cycles. The asymmetric supercapacitor device (MnTB//AC) achieved 114.6 F g(-1) at 1 A g(-1) and a maximum energy density of 35.8 W h(-1) kg(-1) at a power density of 750 W kg(-1) with a voltage window of 1.5 V.
