Abstract
Synthesizing holey graphene oxide includes dispersing graphene oxide in an aqueous solution to yield a first graphene oxide dispersion, irradiating the first graphene oxide dispersion with microwave radiation, thereby at least partially reducing the graphene oxide in the first graphene oxide dispersion to yield a second graphene oxide dispersion that includes partially reduced graphene oxide, combining the second graphene oxide dispersion with an etching agent to form a third graphene oxide dispersion, and irradiating the third graphene oxide dispersion with microwave radiation to yield a fourth graphene oxide dispersion comprising holey graphene oxide.
