Application of a Novel Density Functional Theory to the Pore Size Analysis of Micro/mesoporous Carbons
Recently, we have suggested a model of adsorption in pores with amorphous and microporous solids walls, named the quenched solid density functional theory (QSDFT), that had been successfully applied to modeling adsorption in pores of siliceous materials [1]. This novel approach, which takes into account roughness and corrugation of pore walls, has been extended to carbon adsorbents. QSDFT repre...
متن کاملQuenched solid density functional theory and pore size analysis of micro-mesoporous carbons
We present a new model of adsorption on micro-mesoporous carbons based on the quenched solid density functional theory (QSDFT). QSDFT quantitatively accounts for the surface geometrical inhomogeneity in terms of the roughness parameter. We developed the QSDFT models for pore size distribution calculations in the range of pore widths from 0.4 to 35 nm from nitrogen at 77.4 K and argon at 87.3 K ...
متن کاملCharacterization of the pore structure of three-dimensionally ordered mesoporous carbons using high resolution gas sorption.
The use of colloidal crystals with various primary particle sizes as templates leads to the formation of three-dimensionally ordered mesoporous (3DOm) carbons containing spherical pores with tailorable pore size and extremely high pore volumes. We present a comprehensive structural characterization of these novel carbons by using nitrogen (77.4 K) and argon (87.3 K) adsorption coupled with the ...
متن کاملTuning the Pore Geometry of Ordered Mesoporous Carbons for Enhanced Adsorption of Bisphenol-A
Mesoporous carbons were synthesized via both soft and hard template methods and compared to a commercial powder activated carbon (PAC) for the adsorption ability of bisphenol-A (BPA) from an aqueous solution. The commercial PAC had a BET-surface of 1027 m²/g with fine pores of 3 nm and less. The hard templated carbon (CMK-3) material had an even higher BET-surface of 1420 m²/g with an average p...
متن کاملTemplated mesoporous carbons for supercapacitor application
Mesoporous carbons prepared by an inverse replica technique have been used as electrodes for electrochemical capacitors. Such well sized carbons were prepared from mesostructured SBA-16 silica materials that served as templates whereas polyfurfuryl alcohol was the carbon precursor. Two highly mesoporous carbons characterized by 3 and 8 nm average pore diameter were tested in various electrolyti...
