A METHOD OF FORMING POROUS GRAPHENE-BASED STRUCTURES

摘要

A method of forming a porous graphene-based structure, including directing a laser beam onto one or more layers of graphene oxide to reduce at least a portion of the graphene oxide, wherein the laser beam consists of ultrafast femtosecond (fs) pulses of laser radiation to cause reduction of at least a portion of the graphene oxide by two-photon absorption and form one or more respective porous layers of reduced graphene oxide (rGO) having substantially uniform porosity. In some embodiments, the photoreduction of graphene oxide using the femtosecond laser beam is influenced by acoustic waves in addition to two-photon absorption.
