Abstract
The MOF-derived porous carbon materials for carbon dioxide capture, more specifically comprising a method for preparing thereof and the porous carbon materials for the purpose of CO2 absorbent, wherein the porous carbon materials from zinc-containing three MOFs (MOF-5, MOF-177, and bioMOF-100) are synthesized by a simple pyrolysis and thereby the porous carbon materials have promising CO2 capture capacity and selectivity compared to parent of MOFs prior to pyrolysis, particularly, the CO2 capture capacity of the porous carbon materials is maintained under humid condition.
Claims8
A composition for capturing carbon dioxide (CO2), consisting of:
- a porous carbon material having a metal-free porous carbon structure and being derived from bio-metal-organic framework-100 (bioMOF-100),
- wherein the porous carbon material has micropores which is synthesized by pyrolysis of the bioMOF-100,
- wherein the pyrolysis being carried out at 1000° C. for 6 hours under argon (Ar) atmosphere removes all of zinc contained in the bioMOF-100,
- wherein the porous carbon material maintains CO2 capture capacity under humid condition.
A method of preparing a composition for capturing carbon dioxide (CO2), consisting of;
- S1) preparing bio-metal-organic framework-100 (bioMOF-100) by heating a solution containing adenine, biphenyldicarboxylic acid, and zinc acetate dihydrate;
- and
- S2) removing zinc from the bioMOF-100 by pyrolysis, thereby forming a metal-free porous carbon structure which has micropores synthesized by the pyrolysis,
- wherein the porous carbon material maintains CO2 capture capacity under humid condition,
- wherein the pyrolysis is performed at 1000° C. for 6 hours under argon (Ar) atmosphere.
