Electrodeposition of platinum nanoparticles on reduced graphene oxide as an efficient catalyst for oxygen reduction reaction

Reduced graphene oxide film was synthesized on a glassy carbon electrode by electro reduction of graphene oxide powders in aqueous solution. Then platinum nano particles were deposited on reduced graphene oxide film that was deposited on the glassy carbon electrode via electro reduction of platinum salt. The Physical morphology of the platinum on reduced graphene oxide film was evaluated by sca...

Epoxide reduction with hydrazine on graphene: a first principles study.

Mechanisms for epoxide reduction with hydrazine on a single-layer graphene sheet are examined using quantum mechanical calculations within the framework of gradient-corrected spin-polarized density-functional theory. We find that the reduction reaction is mainly governed by epoxide ring opening which is initiated by H transfer from hydrazine or its derivatives. In addition, our calculations sug...

Performance comparison of graphene and graphene oxide-supported palladium nanoparticles as a highly efficient catalyst in oxygen reduction

In this work, the performance of graphene nanosheets (GNs) and graphene oxide (GO) nanosheets, as a support for palladium nanoparticles (PdNPs) toward oxygen reduction reaction (ORR), was studied. The graphene nanosheets were functionalized by a new and simple method. The PdNPs were synthesized on a glassy carbon electrode (GCE) modified with GNs or GO via a potentiostatic method; without using...

Suitable chemical methods for preparation of graphene oxide, graphene and surface functionalized graphene nanosheets.

This article presents the suitable chemical method for preparation of graphene oxide nanosheets. In order to examine the effects of HNO3/H2SO4 ratio on interlayer spacing and its comparison, the oxidation of graphite with HNO3 and H2SO4 in 1:2 and 1:3 volume ratios was done. Based on the reaction time and interlayer spacing, it was found that the optimum results were obtained when reaction was ...
