CARBON NANOHORN ADSORBENT AND PROCESS FOR PRODUCING THE SAME

摘要

A novel carbon nanohorn adsorbent which does not necessitate a high-temperature treatment, is lightweight and chemically stable, and can selectively adsorb molecules based on the molecular sieve effect; and a process for producing the adsorbent. The process comprises oxidizing a single-wall carbon nanohorn aggregate while controlling oxidative conditions to thereby obtain the carbon nanohorn adsorbent, which have, in the tubular parts, pores having a regulated diameter.
