In　this　contribution,　a　novel　high-temperature　CO2　adsorbent　consisting　of　Mg-Al　layered　double　hydroxide　(LDH)　and　graphene　oxide　(GO)　nanosheets　was　prepared　and　evaluated.　The　nanocomposite-type　adsorbent　was　synthesized　based　on　the　electrostatically　driven　self-assembly　between　positively　charged　Mg-Al　LDH　single　sheet　and　negatively　charged　GO　monolayer.　The　characteristics　of　this　novel　adsorbent　were　investigated　using　XRD,　FE-SEM,　HRTEM,　FT-IR,　BET　and　TGA.　The　results　showed　that　both　the　CO2　adsorption　capacity　and　the　multicycle　stability　of　LDH　were　increased　with　the　addition　of　GO　owing　to　the　enhanced　particle　dispersion　and　stabilization.　In　particular,　the　absolute　CO2　capture　capacity　of　LDH　was　increased　by　more　than　twice　by　adding　6.54　wt%　GO　as　support.　GO　appeared　to　be　especially　effective　for　supporting　LDH　sheets.　Moreover,　the　CO2　capture　capacity　of　the　adsorbent　could　be　further　increased　by　doping　with　15　wt%　K2CO3.　This　work　demonstrated　a　new　approach　for　the　preparation　of　LDH-based　hybrid-type　adsorbents　for　CO2　capture.
