The　nanocomposites　of　graphene　oxide　(GO)-doped　stearate-intercalated　layered　double　oxides　(LDO)　as　a　new　type　of　CO2　adsorbents　at　medium　temperatures　(200-400　degrees　C)　are　reported　for　the　first　time.　The　doping　of　GO　could　improve　stability　of　the　composite　material.　The　CO2　adsorption　uptake　(0.52　mmol/g)　of　LDO-Stearate　(LDO-SA)　was　significantly　increased　by　intercalating　the　long　carbon　chain　organic　anion　of　stearate.　The　6　wt%　GO　LDO-SA　(6GO　LDO-SA)　nanocomposite　possessed　the　largest　CO2　adsorption　uptake　(0.83　mmol/g),　which　was　much　larger　than　that　(0.35　mmol/g)　of　the　conventional　LDO　adsorbent.　Such　a　high　performance　of　6GO　LDO-SA　was　associated　with　its　increase　in　surface　area　and　basic　site　amount.　The　adsorption　process　of　CO2　on　the　nanocomposite　was　dominated　by　the　chemical　adsorption,　and　the　adsorbed　CO2　was　mainly　stored　in　the　form　of　carbonate.　The　regeneration　efficiency　of　6GO　LDO-SA　was　＞　88%　after　10　adsorption　and　desorption　recycling　tests,　which　was　much　higher　than　that　of　LDO.　Simultaneously,　the　6GO　LDO-SA　adsorbent　exhibited　a　fast　kinetics　(0.863　mmol/(g.min))　under　the　medium-temperature　conditions.　We　are　sure　that　the　new　nanocomposite　materials　fabricated　in　the　present　study　are　promising　in　the　applications　of　carbon　dioxide　capture.
