“…In a word, the introduction of heteroatom-containing species for the porous carbon framework can decrease charge transfer resistance and increase the surface density of the active sites, thereby enhancing capacitive performance. [27][28][29] However, although various doped carbons have been investigated, the nitrogen and sulfur co-doped chromium carbide-derived carbons, which can take advantages of the carbidederived carbons and heteroatoms doping, have rarely been reported up to now.…”

Nitrogen and sulfur co-doped carbons derived from chromium carbide (NSCDC) are successfully synthesized by chemical extraction of chromium atom from chromium carbide and followed by a facile hydrothermal treatment using thiourea as nitrogen and sulfur sources. The physicochemical and electrochemical properties of the as-prepared materials are characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen adsorption/desorption isotherm, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier infrared spectroscopy (FTIR), cyclic voltammetry (CV), galvanostatic charge/discharge tests (GCD), electrochemical impedance spectroscopy (EIS) and cycle life measurements. The results demonstrate that nitrogen and sulfur species are successfully incorporated into carbon derived from chromium carbide (CDC), and the obtained NSCDC can still maintain interconnected mesoporous carbon network which is favorable for rapid transport of electrolyte ions. Besides, NSCDC exhibits the enhanced wettability, improved conductivity and excellent supercapacitive performance generated from the incorporation of nitrogen and sulfur. The maximum specific capacitance of 281.2 F g −1 at 1 mV s −1 can be achieved for the NSCDC-4. Moreover, the NSCDC-4 supercapacitor possesses excellent cyclic stability with high capacitance retention of 95% after 6000 consecutive cycles. These exciting results reveal that NSCDC is a kind of promising electrode material for the high performance supercapacitors.

Selective and efficient catalytic hydrogenation of aromatic nitro compounds with multiple groups into target amines under mild conditions is highly desirable yet fairly challenging. Herein, we report a novel iron-based catalyst, which has metal nanoparticles (NPs) encapsulated in porous N-doped carbon nanotubes (NCT). The experimental and density functional theory results reveal that the NCT-supported porous structure provides the metal nanoparticles with more accessible active sites, leading to the Fe/Fe 5 C 2 @NCT-800 catalyst to show extremely high activity, chemoselectivity, and stability toward the hydrogenation of nitro compounds, affording full conversion within 0.2−0.3 h under room temperature.

Micrometer size activated porous carbon spheres doped with nitrogen and sulfur (NSAPC) are synthesized hydrothermally by using saccharose as the carbon precursor and l‐cysteine as the doping agent, followed by KOH activation. These doped porous carbon spheres possess a high specific surface area (SSA) and porosity (mainly microporous) suitable for efficient charge storage. Additionally, doping with nitrogen and sulfur significantly changes the surface chemistry. When tested as electrode material for supercapacitor, the co‐doped porous carbons outperformed the undoped carbon. NSAPC spheres show a high specific capacitance of 270 F/g at a current density of 1 A/g in 1 M H2SO4 and exhibit excellent charge‐discharge cycling stability over 5000 cycles. The enhanced electrochemical performance can be attributed to the combined effect of high specific surface area, presence of micro and mesopores along with nitrogen and sulfur heteroatoms.
