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.
