Abstract

The influence of the synthesis route on the surface characteristics and CO2 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 m2 g−1 and a CO2 adsorption capacity of 2.1 mmol g−1 (at 273 K), the improved Hummer's product was superior to the other two nanocarbons tested.
