Patent ID: 6939394

Claim:
A carbon monolith prepared by a method comprising: molding a pyrolyzable material into a monolithic shape; and pyrolyzing the pyrolyzable material under pyrolysis conditions thereby producing a carbon monolith that is characterized by at least one of the following characteristics: (a) a fill density measured for arsine gas at 25° C. and pressure of 650 torr that is greater than 400 grams arsine per liter of carbon monolith; (b) at least 30% of overall porosity of said carbon monolith comprising slit-shaped pores having a size in a range of from about 0.3 to about 0.72 nanometer, and at least 20% of the overall porosity comprising micropores of diameter <2 nanometers; and (c) a bulk density of from about 0.80 to about 2.0 grams per cubic centimeter, wherein said pyrolysis conditions comprise a temperature below 1000° C.
