Realization of ferromagnetic graphene oxide with high magnetization by doping graphene oxide with nitrogen
The long spin diffusion length makes graphene very attractive for novel spintronic devices, and thus has triggered a quest for integrating the charge and spin degrees of freedom. However, ideal graphene is intrinsic non-magnetic, due to a delocalized π bonding network. Therefore, synthesis of ferromagnetic graphene or its derivatives with high magnetization is urgent due to both fundamental and...
متن کاملSelective nitrogen doping in graphene for oxygen reduction reactions.
Nitrogen-doped graphene materials with abundant pyridinic and quaternary nitrogen species were selectively synthesized by thermal surface polymerization of nitrogen-containing aromatic molecules. Catalytic studies revealed that the oxygen reduction by nitrogen-doped graphene, containing pyridinic and quaternary nitrogen species, proceeds via a four- and two-electron reduction pathway, respectiv...
متن کاملTiO2-graphene nanocomposites. UV-assisted photocatalytic reduction of graphene oxide.
Graphene oxide suspended in ethanol undergoes reduction as it accepts electrons from UV-irradiated TiO(2) suspensions. The reduction is accompanied by changes in the absorption of the graphene oxide, as the color of the suspension shifts from brown to black. The direct interaction between TiO(2) particles and graphene sheets hinders the collapse of exfoliated sheets of graphene. Solid films cas...
متن کاملPlasma-Assisted Reduction of Graphene Oxide at Low Temperature and Atmospheric Pressure for Flexible Conductor Applications.
Reduction of graphene oxide (GO) at low temperature and atmospheric pressure via plasma-assisted chemistry is demonstrated. Hydrogen gas is continuously dissociated in a microplasma to generate atomic hydrogen, which flows from the remote plasma to thin films of GO deposited on a substrate. Direct interaction with ions and other energetic species is avoided to mitigate ion-induced sputter remov...
متن کاملIn-situ and tunable nitrogen-doping of MoS2 nanosheets
Molybdenum disulfide (MoS2) nanosheets have unique physical and chemical properties, which make it a perfect candidate for next generation electronic and energy storage applications. Herein, we show the successful synthesis of nitrogen-doped MoS2 nanosheets by a simple, effective and large-scale approach. MoS2 nanosheets synthesised by this method show a porous structure formed by curled and ov...
