Abstract

The cellular structure of Norway spruce (Picea abies) was transformed via a simple, single-step carbonization process into a carbon monolith with molecular-sieve properties. The monolith exhibited a genuine honeycomb structure derived from the original intrinsic H2O channels of the wood. The micropores formed during carbonization from the walls of the channels were shown to have a high adsorption capacity. The honeycomb monolith was tested for air separation. Micropore diffusion of N2 and O2 was found by the frequency-response (FR) technique to be the rate-controlling process of mass transport.
