Although numerous studies have been dedicated to designing multifunctional porous carbons, most of them still have shown hard-control doping sites and unclear structures. Herein, we prepare a series of structure-controlled F/N co-doped porous carbons (FNCs) with large SBET via an in situ doping process based on F- and N-rich covalent triazine-based frameworks (FCTFs) as precursors. The as-prepared high-F/N-containing FNC-700 with a large SBET (∼1849.1 m2 g–1) as the aqueous-based SC electrode achieves a specific capacitance (Cs) of 326 F g–1 at 1 A g–1, remarkable cyclability with negligible capacitance decay after 10,000 cycles in three-electrode systems, and a maximum energy density of 31.4 Wh kg–1 in two-electrode systems. This study has an insightful hint in exploring multifunctional heteroatom-doped carbons by the in situ doping process.23:T51d,Transition metal-based compounds with high theoretical capacitance and low cost represent one class of promising electrode materials for high-performance supercapacitors. However, their low intrinsic electrical conductivity impedes their capacitive effect and further limits their practical application. Rational regulation of their composition and structure is, therefore, necessary to achieve a high electrode performance. Herein, a well-designed carbon-encased mixed-metal selenide rooted with carbon nanotubes (Ni-Co-Se@C-CNT) was derived from nickel-cobalt bimetallic organic frameworks. Due to the unique porous structure, the synergistic effect of bimetal selenides and the in situ growth of carbon nanotubes, the composite exhibits good electrical conductivity, high structural stability and abundant redox active sites. Benefitting from these merits, the Ni-Co-Se@C-CNT exhibited a high specific capacity of 554.1 C g^-1 (1108.2 F g^-1) at 1 A g^-1 and a superior cycling performance, i.e., 96.4% of the initial capacity was retained after 5000 cycles at 10 A g^-1. Furthermore, a hybrid supercapacitor assembled with Ni-Co-Se@C-CNT cathode and activated carbon (AC) anode shows a superior energy density of 38.2 Wh kg^-1 at 1602.1 W kg^-1.
