Differently shaped two-dimensional (2-D) graphene nanoflakes (GNFs) were prepared on one-dimensional (1-D) carbon nanotubes (CNTs) and silicon nanowires (SiNWs) forming 2-D–1-D composites by using microwave plasma enhanced chemical vapor deposition. The GNFs are vertically aligned on 1-D nanomaterials with their sharp edges (less than 10 layers) unfolded outside and are rich in defects. GNF–CNT (or...
Catalyst-free and self-assembled growth of graphene flakes (GFs) on carbon nanotube (CNT) arrays have been realized by using microwave plasma enhanced chemical vapor deposition. The shape of GFs was highly manipulated by adjusting the growth time, C concentration, and microwave power. We qualitatively discussed the nucleation and growth mechanism of GFs based on the growth parameter–GF shape studies...
Carbon-coated iron nanoparticles were synthesized by a carbon arc discharge method using electrodes made of iron and graphite powder. The amorphous carbon layer of the carbon-coated iron nanoparticles was treated by a 30% H 2 O 2 aqueous solution. Adsorption of the carbon-coated iron particles for heavy metal ions, such as Cr, Ni, Cd, Pb, Co and Mn, was studied. Results showed that...
The growth of few-layer graphene (FLG) on carbon nanotubes (CNTs) was realized by using radio frequency hydrogen plasma sputtering deposition. A defect nucleation mechanism and a two dimensional growth model of the FLG were proposed, and field emission characteristics of these FLG–CNT hybrids were studied. They show excellent field emission properties, with a low turn-on electric field (0.98V/μm)...
