Synthesis of nitrogen doped activated carbon/polyaniline material for CO₂ adsorption

Abstract

The equilibrium adsorption isotherms of carbon dioxide and nitrogen on the nitrogen doped activated carbon (NAC) prepared by the chemical activation of a pine cone-based char/polyaniline composite were measured using a volumetric technique.

Role of the Structure of Graphene Oxide Sheets on the CO2 Adsorption Properties of Nanocomposites Based on Graphene Oxide and Polyaniline or Fe3O4-Nanoparticles

“…Recently, preparation of hybrid composites based on carbonaceous materials, including active carbons, graphite, and graphene, seems to be a promising method to keep exploring. ,, Several strategies such as the structure and morphology control using hydrogels and aerogels, , nanospheres, , and nanotubes through optimization of the composition via cation exchange, surface modification, or nitrogen-based − or metal-based functionalization have been investigated. The functionalization of graphene has proved to be a good strategy to improve the CO 2 adsorption capacity. − Thus, graphene functionalization with polyaniline increases the degree of recyclability and the CO 2 adsorption capacity between three and four times at high pressures compared with pristine graphene, while functionalization with Fe 3 O 4 nanoparticles increases three times the CO 2 capture capacity …”

Synthesis N-Doped Activated Carbon from Sugarcane Bagasse for CO2 Adsorption

“…Moreover, we can observe existence of large number of micropores from the SEM image. The previous study conclude that the addition of urea on activated carbon will displays very thin layered carbon morphology, show interconnected meso-and microporous network structure without obvious macropores rather than pristine activated carbon [28].…”

“…For SBACN, the peak at 1454 and 1538 cm -1 atribut to N-CH2 and C=N bonding suggesting that nitrogen atom not only exist in the surface of activated carbon but also exist in the SBACN polyaromatic structure. The peak at 3212 cm -1 is due to N-H-O-H stretching [28].…”

Construction of activated carbon-supported B3N3 doped carbon as metal-free catalyst for dehydrochlorination of 1,2-dichloroethane to produce vinyl chloride

“…[15][16][17] Doping with heteroatoms such as nitrogen, boron, sulfur, and phosphorus increase active sites and enhance the physical and chemical activities of nanocarbon-based materials. [18][19][20][21] For instance, Xu et al prepared a nitrogen-doped ordered mesoporous carbon (N-OMCs) as the catalyst for dehydrochlorination of 1,2-DCE, with a 1,2-DCE conversion $80% at 300 C. 22 Furthermore, doping carbon with two elements has been found to effectively enhance its properties over those of its singularly doped counterparts, which is a result of the synergistic coupling effects between heteroatoms. 23,24 In particular, boron and nitrogen have attracted great interest because B and N are adjacent to C in the periodic table and has similar atomic characteristics with the carbon atom.…”
