Holey graphene hydrogel with in-plane pores for high ...

2016-7-4 · Capacitive deionization is an attractive approach to water desalination and treatment. To achieve efficient capacitative desalination, rationally designed electrodes with high specific capacitances, conductivities, and stabilities are necessary. Here we report the construction of a three-dimensional (3D) holey graphene hydrogel (HGH). This material contains abundant in-plane pores, offering ...

Fabrication of Holey Graphene: Catalytic Oxidation by ...

We report a facile chemical method for fabricating holey graphene by catalytic oxidation of highly ordered pyrolytic graphite (HOPG) using an Fe III porphyrin complex‐based covalent organic framework (COF) as a bifunctional surface catalyst–template. We demonstrate regular hole formation after oxidation with H 2 O 2 and NaOCl, COF removal, and HOPG exfoliation.
