Carbon Dioxide Capture With Amine Functionlized Graphene Oxide

Abstract: amine functionalized graphene oxide was used as sorbent in order to achieve carbon dioxide capture. In this study, micro size graphite flakes was prepared according to modified hummers method and "hummers' method with additional kmno4." Graphene oxide was then functionalized with ethylenediamine (eda). Different purification methods for graphene oxide were studied as well as different functionalization method times. Graphite oxide and functionalized graphene oxide has been analyzed with fourier transform infrared spectroscopy (ftir) for chemical structure. Thermal gravimetric analysis (tga) was used to test co2 capture capacity. Functionalized graphene oxide that has been purified with 30 washes via centrifuge with 72 hour amine functionalization method time had greatest co2 capture potential with 1.38% weight increase.
