The emerging graphene-based material, an atomic layer of aromatic carbon atoms with exceptional electronic and optical properties, has offered unprecedented prospects for developing flat two-dimensional displaying systems. Here, we show that reduced graphene oxide enabled write-once holograms for wide-angle and full-colour three-dimensional images. This is achieved through the discovery of subw...
Compositing all-carbon materials with distinct dimensions and structures has demonstrated the great potential to bring synergistic promotion individual components for electrocatalytic activity of oxygen reduction reaction (ORR). Fullerene-derived porous carbon fibers (FPCFs) offer unique one-dimensional (1D) nanostructures abundant defects a large specific surface area while graphene features t...
We developed a new method for fabricating reduced graphene oxide (RGO)/Fe-oxide structures from graphene oxide (GO), and for the simultaneous vertical alignment of the RGOs using a single-step process that involves a magnetic field and the fixation of the aligned structures by means of direct evaporation of the films.
Electrochemical water splitting is one of the most economical and sustainable methods for large-scale hydrogen production. However, the development of low-cost and earth-abundant non-noble-metal catalysts for the hydrogen evolution reaction remains a challenge. Here we report a two-dimensional coupled hybrid of molybdenum carbide and reduced graphene oxide with a ternary polyoxometalate-polypyr...
In this work, graphene-oxide-decorated porous ZnO nanosheets were prepared using a hydrothermal method. The graphene oxide/porous nanosheet (GO/ZnO nanosheet) composites characterized with SEM, HRTEM, XRD, Raman spectroscopy, XPS and BET. results indicate that the have porous, single-crystal structure. Thin GO closely cover surface of nanosheets. sensing performance GO/ZnO is investigated. At o...
despite the great potential of graphene as a nanofiller, achieving homogeneous dispersion remains the key challenge for effectively reinforcing polyolefin (such as polyethylene (pe) and polypropylene (pp)) nanocomposites. therefore, in this research, we report a facile combined in situ polymerization and masterbatch method for fabricating pp/reduced graphene oxide (rgo) nanocomposites. in the p...
The time-consuming and challenging preparation of graphene, however, has resulted in the increased interest in graphene oxide (GO). [ 15 ] GO, the oxidized form of graphene, is easily generated through the oxidation and subsequent exfoliation of graphite. The oxygen functional groups enable GO to be dispersed in polar solvents (i.e., water) and further functionalized. However, because the conju...
Membranes with atomic level pores or constrictions are valuable for separation and catalysis. We report a graphene-based membrane with an interlayer spacing of 3.7 angstrom (Å). When graphene oxide nanoplates are functionalized and then reduced, the laminated reduced graphene oxide (rGO) nanoplates or functionalized rGO membrane is little affected by an intercalated fluid, and the interlayer sp...
