We report a clean and eco-friendly method to prepare reduced graphene oxide (RGO) using atomic hydrogen. Pt/gamma-Al2O3 was used as a catalyst for the dissociation of H-2 molecules to form atomic hydrogen, which served as a strong reducing agent for the reduction of graphene oxide (GO). The resulting RGO exhibited a high C/O ratio (similar to 8.6) and high electrical conductivity (similar to 4,420 S/m). This novel reduction process provides facile, one-pot catalytic reduction of GO on the large scale. (C) 2012 Elsevier B.V. All rights reserved.
