2D ultrathin aluminum oxide (2D‐Al 2 O 3 ) nanosheets are prepared by duplicating graphene oxide. An amorphous precursor of the hydroxide of aluminum is first deposited onto graphene oxide sheets, which are then converted into 2D‐Al 2 O 3 nanosheets by calcination, while the graphene oxide is removed. The 2D‐Al 2 O 3 nanosheets have a large specific surface area and a superior adsorption capacity to fluoride ions.
