Nitrogen and Sulfur Doped Mesoporous Carbons, Prepared from Templating Silica, as Interesting Material for Supercapacitors

et al. 2017

Highly accessible surface area and heteroatom-doping are desired properties for carbon electrode materials to be used in electrochemical supercapacitors. In this paper, nitrogen and sulfur doped carbon materials with wide mesopores (13-14 nm) were synthetized according to a hard template approach by pyrolysis of sucrose, 1,10-phenanthroline or dibenzothiophene as carbon, nitrogen-carbon or sulfur-carbon precursors, respectively. The morphology and dimension of mesopores were induced by sacrificial SiO2 nanoparticles (10-20 nm), which are removed at the end of synthesis by an etching solution to reveal a network of hemispherical pores. The interconnected pore structure was confirmed by scanning electron microscopy and transmission electron microscopy. X-ray photoemission spectroscopy and elemental analysis confirmed the presence of nitrogen and sulfur functional groups. The prepared materials were fully characterized by cyclic voltammetry, chronopotentiometry and electrochemical impedance spectroscopy in 0.5 M H2SO4. Notwithstanding the small surface (200 m2g-1) determined by BET method, the nitrogen doped mesoporous carbon showed high specific gravimetric (∼170 F g-1) and surface (∼835 F m-2) capacitances that are comparable to those of materials with much higher surface area (5-10-fold higher)

Lignin-derived heteroatom-doped porous carbons for supercapacitor and CO₂ capture applications

et al. 2018

Summary The present study reports the economic and sustainable syntheses of functional porous carbons for supercapacitor and CO2 capture applications. Lignin, a byproduct of pulp and paper industry, was successfully converted into a series of heteroatom‐doped porous carbons (LHPCs) through a hydrothermal carbonization followed by a chemical activating treatment. The prepared carbons include in the range of 2.5 to 5.6 wt% nitrogen and 54 wt% oxygen in its structure. All the prepared carbons exhibit micro‐ and mesoporous structures with a high surface area in the range of 1788 to 2957 m2 g−1. As‐prepared LHPCs as an active electrode material and CO2 adsorbents were investigated for supercapacitor and CO2 capture applications. Lignin‐derived heteroatom‐doped porous carbon 850 shows an outstanding gravimetric specific capacitance of 372 F g−1 and excellent cyclic stability over 30,000 cycles in 1 M KOH. Lignin‐derived heteroatom‐doped porous carbon 700 displays a remarkable CO2 capture capacity of up to 4.8 mmol g−1 (1 bar and 298 K). This study illustrates the effective transformation of a sustainable waste product into a highly functional carbon material for energy storage and CO2 separation applications.

“…Both ends of the packed BDND were pressed using copper rods with a diameter of 0.8 mm 40 . The BDND electrode was prepared by casting an ink containing BDND on a glassy carbon (GC) disk electrode (diameter: 3 mm) 27,41 . First of all, 10 mg of the BDND was dispersed in 0.5 mL of 30 wt% ethanol to prepare a BDND ink.…”

Herein, a conductive boron-doped nanodiamond (BDND) particle is prepared as an electrode material for an aqueous electric double-layer capacitor with high power and energy densities. The BDND is obtained by depositing a boron-doped diamond (BDD) on a nanodiamond particle substrate with a primary particle size of 4.7 nm via microwave plasma-assisted chemical vapor deposition, followed by heat treatment in air. The BDND comprises BDD and sp2 carbon components, and exhibits a conductivity above 10−2 S cm−1 and a specific surface area of 650 m2 g−1. Cyclic voltammetry measurements recorded in 1 M H2SO4 at a BDND electrode in a two-electrode system shows a capacitance of 15.1 F g−1 and a wide potential window (cell voltage) of 1.8 V, which is much larger than that obtained at an activated carbon electrode, i.e., 0.8 V. Furthermore, the cell voltage of the BDND electrode reaches 2.8 V when using saturated NaClO4 as electrolyte. The energy and power densities per unit weight of the BDND for charging–discharging in 1 M H2SO4 at the BDND electrode cell are 10 Wh kg−1 and 104 W kg−1, respectively, and the energy and power densities per unit volume of the BDND layer are 3–4 mWh cm−3 and 10 W cm−3, respectively. Therefore, the BDND is a promising candidate for the development of a compact aqueous EDLC device with high energy and power densities.
