The synthesis of few-layered graphene sheets with controlled number of layers (3–4) on a large scale was developed using chemical exfoliation by simply controlling the oxidation and exfoliation procedure. The obtained Few-layered Graphene Oxide (FGO) was characterized by atomic force microscopy, X-ray diffraction, thermal gravimetric analysis and Ultraviolet–visible spectroscopy. It is found that...
Hydrogen adsorption isotherms of activated carbon and its mixture with platinum coated activated carbon under various electric potentials and hydrogen pressures were measured at ambient temperature. Results indicated that electric potential enhanced hydrogen adsorption. The higher the applied electric potential is, the higher the hydrogen adsorption capacity is in the experimental range of 0–3000V...
