Ultrafine Pt nanoparticle-decorated robust 3D N-doped porous graphene as an enhanced electrocatalyst for methanol oxidation.

Ultrafine Pt nanoparticles supported on a robust 3D N-doped porous graphene (PtNP/R-3DNG) composite are fabricated. The composite exhibits a considerable enhancement of activity and stability toward the methanol electrooxidation reaction. The robust 3D porous structure and abundant nitrogen atoms are believed to be responsible for the enhanced performance.

Interaction Induced High Catalytic Activities of CoO Nanoparticles Grown on Nitrogen-Doped Hollow Graphene Microspheres for Oxygen Reduction and Evolution Reactions

Nitrogen doped graphene hollow microspheres (NGHSs) have been used as the supports for the growth of the CoO nanoparticles. The nitrogen doped structure favors the nucleation and growth of the CoO nanoparticles and the CoO nanoparticles are mostly anchored on the quaternary nitrogen doped sites of the NGHSs with good monodispersity since the higher electron density of the quaternary nitrogen fa...

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...

Anchoring ZnO Nanoparticles in Nitrogen-Doped Graphene Sheets as a High-Performance Anode Material for Lithium-Ion Batteries

A novel binary nanocomposite, ZnO/nitrogen-doped graphene (ZnO/NG), is synthesized via a facile solution method. In this prepared ZnO/NG composite, highly-crystalline ZnO nanoparticles with a size of about 10 nm are anchored uniformly on the N-doped graphene nanosheets. Electrochemical properties of the ZnO/NG composite as anode materials are systematically investigated in lithium-ion batteries...
