The influence of the synthesis route on the surface characteristics and CO uptake of graphene oxide was studied. Powders derived from the classical Hummer's method approach and the so-called improved Hummer's method were benchmarked against zeolite 13X and certified carbon nanotubes. With a specific surface area of 283 m g and a CO adsorption capacity of 2.1 mmol g (at 273 K), the improved Hummer's product was superior to the other two nanocarbons tested.
