Abstract

Porous-Graphene Single Layers on SI/SIO2 Porous graphene is synthesized from oxo-functionalized graphene (oxoG), as reported in article number 2100783 by Siegfried Eigler and co-workers. The 3D atomic force microscopy image of oxoG with pores on the 100 nm scale looks like a mountain with ridges. The red pits represent the pores. The higher peaks around the pits represent the active sites, which are easily hit by lightning. The lightning has a two-fold meaning, the etching of pores and the enhancement of photoluminescence of MoS2 by the porous graphene.
