CARBON DIOXIDE ABSORBENT HAVING CORE-SHELL STRUCTURE

摘要

The present invention relates to a carbon dioxide absorbent of multicore-shell nanosphere composite structures, comprising a carbon nanosphere; and a plurality of metal oxide cores embedded in the carbon nanosphere wherein the metal oxide core is actually crystalloid nanoparticles which are uniformly dispersed in the carbon nanosphere, and the carbon nanosphere has a carbon dioxide absorbent which is carbon shells having a thickness used for blocking the metal oxide cores from directly touching external gas.
