Effects of surface charging treatment on outer and inner surfaces of a nanoporous carbon
نویسندگان
چکیده
As the outer surface of a nanoporous carbon is treated with 16-mercaptohexadecanoic acid, the carbon particles can form a stable suspension in water. When the water phase is compressed, the liquid infiltration behavior in the nanopores becomes significantly different from that of untreated material, suggesting that the inner surface is also modified. After the treatment, the infiltration pressure does not decrease. Therefore, the chain configurations at the inner and outer surfaces must be different, which explains the variations in infiltration pressure and volume.

Effects of Confinement in Carbon Nanotubes on the Performance and Lifetime of Fischer-Tropsch Iron Nano Catalysts
The effects of confinement in carbon nanotubes on Fischer-Tropsch (FT) activity, selectivity and lifetime of Carbon NanoTubes (CNTs) supported iron catalysts are reported. A method was developed to control the position of the catalytic sites on either inner or outer surface of carbon nanotubes. TEM analyses revealed that more than 80% of iron oxide particles can be controlled to be position...
متن کاملThe computational study of adsorption of carbon monoxide on pristine and Ge-doped (6,0) zigzag models of BNNTs
The aim of this research is studying the effects of Ge-doped on CO adsorption on the outer and inner surfaces of (6, 0) zigzag model of boron nitride nanotube (BNNTs) by using DFT theory. For this purpose, eight models of CO adsorption on the surfaces of BNNTs are considered. At first step, all structures were optimized at B3LYP and 6-31G (d) standard base set and then the electronic structure,...

In this paper, synthesized (raw) multi-walled carbon nanotube (rMWCNTs) surfaces were modified with chitosan and β-cyclodextrin using Chen’s soft cutting technique. Raw and surface modified multi-walled carbon nanotubes were observed by transmission electron microscope (TEM). The results showed that chitosan and β-cyclodextrin could attach to the outer surface of nanotubes, wrapping the nanotub...
متن کاملNon-Dissociative Gas Adsorption with Different Chemisorption Geometries on Nanoporous Surfaces
Isotherm equation is one of the important scientific bases for adsorbent selection. There are different isotherms that do not account for an adsorbate, different chemisorption geometries on the nanoporous surface. It is interesting to introduce a general isotherm, which considers different chemisorption geometries of an adsorbate on nanoporous surfaces. In this study, an isotherm for non-dissoci...
