Title:	CARBON-CONTAINING MATRIX WITH FUNCTIONALIZED PORES
Abstract:	A composition of matter comprises a carbon-containing matrix. The carbon- containing matrix may comprise one or more carbon materials selected from the group comprising graphite crystalline carbon materials, carbon powder, carbon fibers, artificial graphite powder, and combinations thereof. In addition, the carbon- containing matrix comprises a plurality of pores. The composition of matter also comprises a reactive additive that is not a metal pressure disposed within at least a portion of the plurality of pores.

The carbon-containing matrix with functionalized pores may serve as a filter or be utilized as storage for certain materials.

DETAILED DESCRIPTION

[0015] Porous carbon can be utilized in many applications, hi some cases, porous carbon can be used as a filter. For example, charcoal can be processed to achieve a high degree of microporosity, such that one gram of the porous carbon has a surface area of approximately 500 m². For many applications, the large surface area of the porous carbon is relied on to filter fluids and/or gases.

[0016] Additionally, the porous carbon may be activated by charging the surface of the porous carbon with a positive charge to adsorb impurities from fluids and/or gases being filtered. In some cases, the charcoal used to form the porous carbon may be treated chemically to enhance the adsorption achieved via the porous carbon.

Activated porous carbon can also be used as fuel storage to store natural gas and H₂ gas.

Abstract:
A multiscale theoretical approach was used to investigate hydrogen storage in a novel three-dimensional carbon nanostructure. This novel nanoporous material has by design tunable pore sizes and surface areas. Its interaction with hydrogen was studied thoroughly via ab initio and grand canonical Monte Carlo calculations. Our results show that, if this material is doped with lithium cations, it can store up to 41 g H2/L under ambient conditions, almost reaching the DOE volumetric requirement for mobile applications.
