▎ 摘　　要

NOVELTY - The apparatus comprises: a graphene oxide (GO) target; and a light source remotely located from the GO target, where the light source emits a light pulse, directed at the GO target, with sufficient power to initiate a deoxygenation reaction in the GO target to transform the GO target to graphene. The GO target comprises a porous structure of graphene oxide, and a thin film of graphene oxide. The porous structure of graphene oxide comprises a freeze-dried structure of graphene oxide. The light source comprises: a lithographic light source to pattern the thin film of graphene oxide. USE - The apparatus is useful for reducing GO to obtain graphene. ADVANTAGE - The obtained graphene is: non-toxic and stable; affordable; and high in yield. DETAILED DESCRIPTION - The apparatus comprises: a graphene oxide (GO) target; and a light source remotely located from the GO target, where the light source is configured to emit a light pulse, directed at the GO target, with sufficient power to initiate a deoxygenation reaction in the GO target to transform the GO target to graphene. The GO target comprises a porous structure of graphene oxide, and a thin film of graphene oxide. The porous structure of graphene oxide comprises a freeze-dried structure of graphene oxide. The light source comprises: a lithographic light source configured to pattern the thin film of graphene oxide, where the thin film is formed on catalytic metal substrate that scavenges oxygen during the deoxygenation reaction of the GO target; and a laser.
