Porous‐Graphene Single Layers on SI/SIO 2 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 MoS 2 by the porous graphene.
