Graphene-based materials : synthesis, characterization, properties, and applications
Graphene, a two-dimensional, single-layer sheet of sp2 hybridized carbon atoms, has attracted tremendous attention and research interest, owing to its exceptional physical properties, such as high electronic conductivity, ...
Reduced graphene oxide-templated photochemical synthesis and in situ assembly of Au nanodots to orderly patterned Au nanodot chains
A novel photochemical method for the synthesis of fluorescent Au nanodots (size ≈1.2nm) is proposed (see image). The results clearly demonstrate that reduced graphene oxide sheets modified with functional organic molecules ...
Synthesis of Fe3O4 and Pt nanoparticles on reduced graphene oxide and their use as a recyclable catalyst
A bifunctional Fe3O4–Pt/reduced graphene oxide (rGO) composite, i.e. Fe3O4 nanoparticles ([similar]4.8 nm in size) and Pt nanoparticles ([similar]5 nm in size) loaded on a rGO surface, has been synthesized. It shows great ...
In situ synthesis of metal nanoparticles on single-layer graphene oxide and reduced graphene oxide surfaces
A straightforward one-step chemical method to in situ synthesis of Ag nanoparticles (Ag NPs) on single-layer graphene oxide (GO) and reduced graphene oxide (r-GO) surfaces is proposed. After simply heating the single-layer ...
Chemoselective photodeoxidization of graphene oxide using sterically hindered amines as catalyst : synthesis and applications
We report a green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation catalyzed with 2,2,6,6-tetramethyl-4-piperidinol. While the sp2-hybridized oxygen functional groups ...
