An environmentally‐benign carbocatalyst based on amine‐functionalized graphene oxide (AP‐GO) was synthesized and characterized. This catalyst shows superior activity for the chemical fixation of CO 2 into cyclic carbonates at the atmospheric pressure. The developed carbocatalyst exhibits superior activity owing to its large surface area with abundant hydrogen bonding donor (HBD) capability and the presence of well‐defined amine functional groups. The presence of various HBD and amine functional groups on the graphene oxide (GO) surface yields a synergistic effect for the activation of starting materials. Additionally, this catalyst shows high catalytic activity to synthesize carbonates at 70 °C and at 1 MPa CO 2 pressure. The developed AP‐GO could be easily recovered and used repetitively in up to seven recycle runs with unchanged catalyst activity.
