Metal-organic frameworks are formed via the connection of transition metals with oxygen-or nitrogencontaining organic ligands; the organic ligands are rich in carbon and contain heteroatoms such as N and P. Herein, NMFC-T porous carbon was prepared with (Ni-3(BTC)(2)(Me2NH)(3)) as the carbon precursor using the strategy of pre-carbonization and KOH activation. Influence of carbonization temperature on properties of NMFC-T porous carbon was investigated, and the electrochemical performance of NMFC-800 porous carbon was studied using a three-electrode system. Results revealed that NMFC-800 porous carbon has a high specific surface area of 1143 m(2)g(-1) with a mesopore proportion over 80%. Using KOH solution as an electrolyte, the specific capacitance was as high as 211 F g(-1) at a current density of 1 A g(-1), and the capacitance retention was 81.04% after 5000 cycles. NMFC-800 porous carbon has excellent supercapacitive performance and good cycle stability. (C) 2018 Elsevier Ltd. All rights reserved.
