Transforming amorphous carbon into graphene by current- induced annealing
ABSTRACT: We report on the catalyst-free growth of graphene from amorphous carbon (a-C) by current-induced annealing. This is a novel mechanism that we could witness by in-situ transmission electron microscopy and simulate with molecular dynamics calculations. We observe that small a-C clusters on a graphene substrate rearrange and crystallize into graphene patches due to the high temperatures ...
متن کاملHeat-induced Transformations of Adsorbed Hydrocarbon Residues on Graphene
We describe new phenomena of structural reorganization of carbon adsorbates as revealed by in situ atomic-resolution transmission electron microscopy (TEM) performed on specimens at extreme temperatures. In our investigations, a graphene sheet serves as both a quasi-transparent substrate for TEM and as an in situ heater. The melting of gold nanoislands deposited on the substrate surface is used...
متن کاملIn situ observation of carbon-nanopillar tubulization caused by liquidlike iron particles.
The tubulization process of amorphous carbon nanopillars was observed in situ by transmis-sion electron microscopy. Amorphous carbon nanopillars were transformed into graphitic tubules by annealing at 650-900 degrees C in the presence of iron nanoparticles. A molten catalyst nanoparticle penetrated an amorphous carbon nanopillar, dissolving it, and leaving a graphite track behind. An iron nanop...

متن کاملA Flexible Platform Containing Graphene Mesoporous Structure and Carbon Nanotube for Hydrogen Evolution
It is of great significance to design a platform with large surface area and high electrical conductivity for poorly conductive catalyst for hydrogen evolution reaction (HER), such as molybdenum sulfide (MoS x ), a promising and cost-effective nonprecious material. Here, the design and preparation of a free-standing and tunable graphene mesoporous structure/single-walled carbon nanotube (GMS/SW...
