▎ 摘　　要

Doubts about a two-component structural model of graphene oxide have been raised recently in a paper in Carbon. Here we revisit the arguments presented and show why, contrary to the claims in this recent paper, the evidence is indeed consistent with as-produced graphene oxide consisting of large (micron sized), lightly oxidised, monolayer graphene-like sheets to which are complexed small, highly oxidised, carbonaceous molecules.
