▎ 摘　　要

NOVELTY - A carbon dioxide adsorbent comprises a hybrid matrix formed by hybridizing a separated reduced graphene oxide nanosheet and a layered metal oxide nanosheet, and a co-hybridization nanocomposite comprising 1-5 pts. wt. layered double oxide contained in the hybrid matrix. The carbon dioxide adsorbent has carbon dioxide adsorption/regeneration property, which is improved by the layered metal oxide nanosheet. USE - Carbon dioxide adsorbent. ADVANTAGE - The carbon dioxide adsorbent has high surface area ratio, and suppresses the self-aggregation of nanosheets. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of carbon dioxide adsorbent.
