Here we demonstrate the in situ formation of ultra-small gold nanoparticles (<2 nm) finely dispersed on a binary solid carrier, i.e. a mesoporous SiO2 coated graphene oxide (GO) nanosheet. The as-synthesized Au-SiO2-GO composite has shown high catalytic activity and reusability for chemical reactions under mild conditions.

The present communication reports on the first preparation of reduced graphene oxide (rGO) via surface plasmon resonance (SPR)-induced visible light photocatalytic reduction of GO with the use of Ag nanoparticles (AgNPs) as a plasmonic photocatalyst in the presence of an electron donor (ED).

Noble metal nanoparticles are directly and homogeneously grown onto graphene-oxide (GO) sheets in oleylamine. After the oleylamine is removed, the GO sheets are exfoliated by the nanoparticle pillars to further form hierarchical GO nanostructures with molecule accessible nanopores. With specific sensing-groups modified, the porous-layered nanostructure can be constructed onto resonant microcant...

A simple strategy for preparation of reduced graphene oxide (RGO)/TiO2 hybrid thin films was developed by UV-assisted incorporation of TiO2 nanoparticles (NPs) onto RGO films. The UV-assisted incorporation of TiO2 NPs onto RGO films makes the hybrid films stable against prolonged exposure to UV light without the decrease of their conductivity and transparency.

A facile one-step approach was proposed to prepare hydrophilic and peptide-functionalized upconversion nanoparticles (UCNPs), which were used in the design of a biosensor for the sensitive and selective determination of human immunodeficiency virus antibodies in human serum based on FRET from the UCNPs to the graphene oxide.

Composites with nanoparticles and polymers can improve the functionalities and existing formulations. In this work we synthesized Graphene Oxide and is incorporated into an epoxy based negative tone photoresist in different weight percentages. Thermal conductivity studies were carried out on those composites and it was found that 13 % by weight is the optimized loading to have an enhanced therm...

The highly reduced graphene oxide using solvated electrons as reductive agents shows low defects and well dispersion that are vital as the support of Pt nanoparticles in direct methanol electro-oxidation. The electrochemical experiments demonstrate that the Pt/RGO composites not only greatly enhance the catalytic activity but also dramatically improve the durability of the catalyst.

In this study, an efficient and facile technique for preparing graphene oxide in suspension and powder forms was presented based on a modification on Hummers' method followed by an additional ultrasonic process. The method involved the provision of graphene oxide from graphite by reaction of potassium permanganate and sulfuric acid with stabilizing the medium complex. Furthermore, this study ev...

Nickel oxide (NiO) as one of the anode electrode materials for lithium ion batteries (LIBs) has attracted considerable research attention. However, the poor electron conductivity and bad capacity retention performance greatly hinder its wide application. Herein, we prepared a novel three-dimensional (3D) hierarchical porous graphene@NiO@carbon composite via a simple solvothermal process, in whi...

This study developed a facile approach for preparing Ti(3+) self-doped TiO2-graphene photocatalyst by a one-step vacuum activation technology involved a relative lower temperature, which could be activated by the visible light owing to the synergistic effect among Ti(3+) doping, some new intersurface bonds generation and graphene oxide reduction. Compared with the traditional methods, the vacuu...
