نویسندگان
چکیده
In this work, N/O codoped porous carbons (NOPCs) were derived from corn silk accompanied by Na2CO3 activation. The structures and surface chemical features of as-prepared carbon materials tailored adjusting the mass ratio. After activation, optimized sample (NOPC1) with abundant ultramicropores pyrrolic N displays an enhanced CO2 adsorption capacity 3.15 mmol g−1 1.95 at 273 K 298 1 bar, respectively. Moreover, also exhibited high IAST selectivity (16.9) Henry’s law (15.6) for CO2/N2 as well moderate heat adsorption. Significantly, joint effect between ultramicropore structure content was found to govern performance NOPCs samples.

Highly porous S-doped carbons
Porous sulphur-doped carbons have been prepared by using polythiophene (PTh) as carbon precursor and KOH as activating agent. The activation process was carried out under several operating conditions, i. e. a KOH/PTh weight ratio of 2 or 4, and reaction temperatures in the 600-850 oC range. The porous carbons thus obtained exhibit very large apparent surface areas and high pore volumes of up to...
متن کاملSustainable porous carbons with a superior performance for CO2 capture
Sustainable porous carbons have been prepared by chemical activation of hydrothermally carbonized polysaccharides (starch and cellulose) and biomass (sawdust). These materials were investigated as sorbents for CO2 capture. The activation process was carried out under severe (KOH/precursor=4) or mild (KOH/precursor=2) activation conditions at different temperatures in the 600-800oC range. Textur...
متن کاملDeformation of porous carbons upon adsorption.
N2 and CO2 sorption measurements with in situ dilatometry implemented in a commercial volumetric sorption instrument were performed at 77 and 273 K, respectively. The resolution of the linear deformation was about ±0.2 μm. To separate effects due to microporosity, external surface area and mesopores synthetic porous carbons (xerogels) with different external surface areas and microporosities we...
متن کاملCO2 adsorption by activated templated carbons.
Highly porous carbons have been prepared by the chemical activation of two mesoporous carbons obtained by using hexagonal- (SBA-15) and cubic (KIT-6)-ordered mesostructured silica as hard templates. These materials were investigated as sorbents for CO(2) capture. The activation process was carried out with KOH at different temperatures in the 600-800°C range. Textural characterization of these ...
متن کاملFacile fabrication of novel highly microporous carbons with superior size-selective adsorption and supercapacitance properties.
A facile approach to fabricate novel highly microporous carbons has been developed by direct carbonization of lowly cross-linked polystyrene. The as-prepared highly microporous carbons demonstrate unusually high micropore rate (97%), high surface area (1108 m(2) g(-1)) and uniform pore size distribution, and thus exhibit excellent size-selective adsorption and electrochemical properties.
