Space-confined creation of nanoframes in situ on reduced graphene oxide

Nanoframes (NFs) are created in situ on reduced graphene oxide (rGO) through confining the evolutions of precursor nanosheets, such as ZnS(EN)0.5 (EN = ethylenediamine), and nanoparticles within quasi-two-dimensional spaces generated from graphene oxide. The resultant composites of ZnS-NF@rGO exhibit excellent photocurrent responses. This work provides a new strategy to synthesize and modulate nanostructures and nanomaterials for rGO composites.
