Graphene oxide (GO) is a promising precursor for the mass production of graphene. As an important step in this direction, the electrical conductivity of GO has been enhanced by six orders of magnitude, thus closely approaching that of exfoliated graphene. The novel two‐step process reported by Cristina Gómez‐Navarro and co‐workers on p. 4683 involves hydrogen reduction and healing by a gaseous carbon feedstock. The inside cover shows a snapshot of the crucial second step. The oxidized regions in GO are represented in red, and the blue patches correspond to vacancies.
