Carbon in dense as well as porous solid form is used in a variety of applications. Activated porous carbons are made through pyrolysis and activation of carbonaceous natural as well as synthetic precursors. Pyrolysed woods replicate the structure of original wood but as such possess very low surface areas and poor adsorption capacities.

This chapter reviews results obtained using virtual porous carbon (VPC) models associated with molecular simulation techniques. By discussing different examples, we try to demonstrate that this can be a really helpful approach in adsorption science. At the start of the chapter, we briefly describe the concept of VPC, the methods of absolute pore-size ...

Adsorption of nitrogen by porous and non-porous carbons
Carbon, 1987Abstract Nitrogen isotherms have been determined at 77 K on a number of carbon blacks and microporous carbons. Application of the Dubinin-Radushkevich (DR) method has shown that linear plots are given by both nonporous and microporous samples. The range of linearity is considerably reduced by increasing the micropore size, while graphitisation of ...

Phenol adsorption on porous and non-porous carbons
Carbon, 2003Phenol physisorption on a series of porous and non-porous amorphous carbons was studied at 298 K. Grand Canonical Monte Carlo computer simulations were performed to simulate phenol adsorption from the gas phase. Phenol is adsorbed in a solid-like state within the pores and there is no well-developed multilayer regime. The ‘t’ plot method was adapted to

Biomechanical investigations of bone‐porous carbon and porous metal interfaces
Journal of Biomedical Materials Research, 1973AbstractThe mechanical strengths of four types of ingrown porous carbon and two types of porous metal bone implants were correlated with the type of osseous ingrowth into the porous interfaces. Intracortical cylinders were implanted into canine long bones and examined at 3, 6, and 12 weeks.

Recent Progress on Porous Carbons for Carbon Capture
LangmuirHigh emission of carbon dioxide (CO2) has caused CO2 levels to reach more than 400 ppm in air and led to a serious climate problem. In addition, in confined spaces such as submarines and aircraft, the CO2 concentration increase in the air caused by human respiration also affects human health.

Fabrication of porous carbon nanotube network
Chemical Communications, 2008We used the spin-coating method combined with ultrasonic atomization as a continuous, one-step process to generate a two-dimensional honeycomb network that was constructed from pure multi-walled carbon nanotubes.

Porous Carbons for Carbon Dioxide Capture
2014Porous carbons play an important role in CO2 adsorption and separation due to their developed porosity, excellent stability, wide availability, and tunable surface chemistry. In this chapter, the synthesis strategies of porous carbon materials and evaluation of their performance in CO2 capture are reviewed.

A porous LiFePO4 and carbon nanotube composite
Chemical Communications, 2010A novel composite electrode structure with highly-conductive 3D nanotube networks superimposed into interlaced porous LiFePO(4) media was designed and realized via an in situ sol-gel process, yielding a high-performance multidimensional composite cathode for high-energy and high-power lithium-ion batteries.

Deformation of Porous Carbons upon Adsorption
Langmuir, 2011N2 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 ...
