“…2c and d). XPS spectra of the S 2p peak show that there are mainly three types of S, one with 163.8 eV, which can be assigned to the C-S-C in the thiazine/thiazole rings [27], while the higher binding energy of 164.9 eV can be attributed to the presence of S-C-N binding motifs. Additionally, a broad peak centered at 168 eV indicates the presence of S + or a sulfur oxide species.…”

C 2 N"-species have emerged as a promising material with carbon-like applications in sorption, gas separation and energy storage, while with much higher polarity and functionality. Controlled synthesis of "C 2 N" structure is still based on complex and less-sustainable monomers, which prohibits its broader industrial application. Here we report a class of well-defined C 2 (N x O y S z ) 1 carbons with both high content of N/O/S heteroatoms and large specific surface area of up to 1704 m 2 g −1 , which can be efficiently synthesized through a simple additive condensation process using simple gallic acid and thiourea as the building blocks, without subtractive activation. This 1,4-para tri-doped C 2 (N x O y S z ) 1 structure leads to sufficient CO 2 adsorption capacity (3.0 mmol g −1 at 273 K, 1 bar) and a high CO 2 /N 2 selectivity (47.5 for a 0.15/0.85 CO 2 /N 2 mixture at 273 K). Related to the polarity, the polar frameworks can be used as supercapacitor electrodes, with record specific capacitances as high as 255 F g −1 at 3.5 V for a symmetric supercapacitor in ionic liquid electrolyte. This work discloses a general way for preparing a novel family of multifunctional, high heteroatomdoped porous materials for various applications. 1 Oschatz M, Antonietti M.

Progress in sustainable energy development often relies upon the idea of making use of green materials and agents to fabricate the components of high‐performance energy storage devices. Herein, we show that a relatively high energy density of 11.9 Wh kg−1 at a 0.1 A g−1 current density in a 1 M H2SO4 solution and a stable capacitance performance for up to 10000 cycles can be achieved in a symmetric supercapacitor (SC) made of two identical hierarchical porous carbon (HPC) electrodes derived from bean curd and 10 wt.% potassium carbonate (K2CO3); both of which are non‐toxic, edible materials. Such HPC, defined as HPC‐10, which was made through a one‐pot activation process followed by carbonization at 750 °C, exhibits high specific surface area of 2514 m2 g−1, hierarchical porous framework (i. e., simultaneous presence of abundant micropores, mesopores, and macropores), and contains N and O dopant components. In a three‐electrode system, HPC‐10 showed specific capacitances of 486 F g−1 in a 1 M H2SO4 and 404 F g−1 in a 6 M KOH, both obtained at a 0.1 A g−1 current density. This work also evaluates systematically the porous structure and electrochemical performance of HPC as a function of K2CO3 concentration from 0 wt.% to 15 wt.%.

Porous carbons with nitrogen-doped (N-doped) structures are promising materials for advanced energy conversion and storage applications, including supercapacitors and fuel cell catalysts. In this study, microporous N-doped carbon was successfully fabricated through carbonization of covalent organic frameworks (COFs) with an azine-linked two-dimensional molecular network (ACOF1). In the carbonized ACOF1, micropores with diameters smaller than 1 nm are selectively formed, and a high specific surface area (1596 cm g ) is achieved. In addition, the highly porous structure with N-doped sites results in enhancement of the electrochemical capacitance. Detailed investigation for the micropore-forming process reveals that the formation of nitrogen gas during the thermal degradation of the azine bond contributes to the microporous structure formation. Therefore, the present direct carbonization approach using COFs allows the fabrication of microporous heteroatom-doped carbons, based on molecularly designed COFs, toward future electrochemical and energy applications.
