Energy storage materials have advanced renewable energy technologies. Herein, we described the one-pot synthesis of covalent organic frameworks (COFs)/graphitic carbon nitride (g-C 3 N 4 ) nanocomposite. The condensation of melamine and benzene-1,3,5-tricarboxyaldehyde with and without g-C 3 N 4 offered the synthesis of COF and COF/g-C 3 N 4 . Furthermore, N-doped carbon and N-doped carbon/g-C 3 N 4 were synthesized via the carbonization of COF and COF/g-C 3 N 4 , respectively. The materials i.e., before and after carbonization were used as electrode materials for supercapacitors and lithium-ion batteries (LIBs). They showed specific capacitance of 211, 257.5, 450, and 835.2 F•g −1 for COF, COF/g-C 3 N 4 , N-doped carbon, and N-doped carbon/ g-C 3 N 4 , respectively. Asymmetric supercapacitor device using N-doped carbon/g-C 3 N 4 exhibited good energy (45.97 Wh•kg −1 ) with high power (659.3 W•kg −1 ). The N-doped C/g-C 3 N 4 electrode was also applied for LIBs, offering a discharge capacity of 390 mAh•g −1 (at 50 mA•g −1 ).

“…9 Recently, metal-organic framework (MOF)engaged synthesis has been regarded as an effective tactic to construct various micro-/nanostructures for electrochemical applications. [10][11][12][13] Zeolitic imidazolate framework (ZIF)-67, formed by the coordination of Co 2+ ions with 2-methylimidazole (2-MIM) linkers, is one of the mostly utilized MOF templates for preparing versatile electrode materials on account of its excellent stability and simple synthesis. 14,15 ZIF-67 derivatives usually present porous and hollow nanostructures, which can expose a large number of electroactive sites and accommodate the volume expansion of electrode materials during electrochemical processes.…”

“…Modern technologies, especially focused on searching for new energy sources, storing energy or processing it, require the creation and research of new materials, cheaper, more durable and exhibiting desirable physicochemical properties. These new electro-technically useful materials include covalent organic frameworks [1,2], metal-organic frameworks [3][4][5] or transition metal MXenes [6][7][8]. Traditional materials that have been used for many years in devices for generating, Abstract Composites of poly(p-phenylene vinylene) (PPV) and different carbon nanostructures, such as fullerene C 60 , multi-walled carbon nanotubes (MWC-NTs), single-walled carbon nanotubes (SWCNTs), graphene oxide (GO), and graphene nanoplatelets (GNPLs), were produced by Wittig's soluble precursor procedure in solutions containing dispersed particles of carbon nanomaterials.…”

Composites of poly(p-phenylene vinylene) (PPV) and different carbon nanostructures, such as fullerene C60, multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWCNTs), graphene oxide (GO), and graphene nanoplatelets (GNPLs), were produced by Wittig’s soluble precursor procedure in solutions containing dispersed particles of carbon nanomaterials. These composites were investigated using infrared and Raman spectroscopy, scanning and transmission electron microscopy, thermogravimetry analysis, adsorption/desorption of N2 measurement, and electrochemistry. Composites are produced in the form of nanostructural porous materials. A significant increase in the BET (Brunauer–Emmett–Teller) surface is observed for composites in comparison to unmodified PPV. The highest BET surface area of 125 m2·g−1 was obtained for the PPV/SWCNT composite. Compared to pristine PPV, composites also exhibit higher thermal stability. The effect of the content of composite components on their electrochemical properties was also investigated. The electronic interaction between components of composite significantly affects their electrochemical properties, particularly in the case of oxidation processes. PPV incorporated into network of carbon nanostructures exhibit two well separated oxidation steps. The carbon component is responsible for the shift of the PPV reduction and oxidation processes toward less negative and less positive potentials, respectively, significantly lowering the energy of the band gap.
