Density-functional theory (DFT) calculations reveal that the formation of an armchair epoxy chain on a graphene sheet is energetically favorable when oxidation occurred on both sides of the graphene sheet. However, the formation of a zigzag epoxy chain is favorable when oxidation occurred on the sam...
