Abstract：Cellose-basedporouserogelcompositeswerepreparedfromoficewastepaperandgrapheneoxide（GO），folowedbyaminefunctionalization of the surface with （ 3 -aminopropyl） triethoxysilane （APTES） to enhance CO capture.In addition，adsorption kinetics，iso2steric heatof adsorption，cycling stability， CO2/N2 selectivity，and water uptake were evaluated. The APTES-functionalized cellulose/GOcomposite aerogel exhibited CO uptaked of 1.2，1.5，and 2.5 mmol/g at 25C under 0.001 ，0.01，and O.1 MPa，respectively，with a CO （204号 2selectivtyof87at0O1MPa.Thematerialshowedrobustcyclingperformancenlyslightcapacityfadeunderpresureswingadsoption，while complete regeneration was achieved after temperature- and/or pressure-swing desorption.
