Introduction Various forms of carbon nanomaterials such as fullerenes, carbon nanotubes, Nano diamonds and other carbon nanomaterial’s have been rapidly developed not only for their unusual electrical and mechanical properties, but also for their potential use in Nano fluidic device [1-9]. Since 2003 Kawase et al. [10] reported the synthesis of the first Nano rings, a family of similar material...

A scalable technique of chemical vapor deposition (CVD) growth of ultra-thin graphitic film is proposed. Ultra-thin graphitic films grown by a one-step CVD process on catalytic copper substrate have higher crystallinity than pyrolytic carbon grown on a non-catalytic surface and appear to be more robust than a graphene monolayer. The obtained graphitic material, not thicker than 8 nm, survives d...

Capture of carbon dioxide from fossil fuel power plants via adsorption and sequestration of carbon dioxide in unmineable coal seams are achievable near-term methods of reducing atmospheric emissions of this greenhouse gas. To investigate the influence of surface heterogeneity upon predicted adsorption behavior in activated carbons and coal, isotherms were generated via grand canonical Monte Car...

Nano-carbon as lighting source is demonstrated in this paper. The characterized nano-radiation from nano-carbon, excited by different lasers in vacuum, is observed when laser intensity is over a threshold. With lower excitation threshold and smaller white light source, nano-carbon is more applicable to be as lighting system than the others in scientific experiments. White light emission of nano...

The U.S. National Institute of Standards and Technology (NIST) provides a number of particulate matter (PM) standard reference materials (SRM) for use in environmental and toxicological methodology and research. We present here the first analysis with respect to the molecular structure of the carbon in three such NIST SRM samples, i.e., diesel engine exhaust soot from heavy duty equipment engin...

Graphitic strips (ribbons) can thought of as segments of carbon nanotubes (CNTs), and therefore may posses many of the useful mechanical and electronic properties of CNTs. We have prepared discrete graphitic strips from o-oligophenylenes, using the intramolecular Scholl oxidation. o-Oligophenylenenes were prepared by Ullmann coupling of a tetra methoxy substituted 2,2’-dibromobiphenyl. The meth...

Abstract Atomically monodispersed heterogeneous catalysts with uniform active sites and high atom utilization efficiency are ideal catalytic materials. Designing such type of catalysts, however, remains a formidable challenge. Herein, using wet-chemical method, we successfully achieved mesoporous graphitic carbon nitride (mpg-C 3 N 4 ) supported dual-atom Pt 2 catalyst, which exhibited excellen...

Many methods have been proposed for efficient storage of molecular hydrogen for fuel cell applications. However, despite intense research efforts, the twin U.S. Department of Energy goals of 6.5% mass ratio and 62 kg/m3 volume density has not been achieved either experimentally or via theoretical simulations on reversible model systems. Carbon-based materials, such as carbon nanotubes, have alw...

Graphitic carbon nitride (g-C3N4) is a rising two-dimensional material possessing intrinsic semiconducting property with unique geometric configuration featuring superimposed heterocyclic sp(2) carbon and nitrogen network, nonplanar layer chain structure, and alternating buckling. The inherent porous structure of heptazine-based g-C3N4 features electron-rich sp(2) nitrogen, which can be exploit...

Graphitic carbon nitride has been predicted to be structurally analogous to carbon-only graphite, yet with an inherent bandgap. We have grown, for the first time, macroscopically large crystalline thin films of triazine-based, graphitic carbon nitride (TGCN) using an ionothermal, interfacial reaction starting with the abundant monomer dicyandiamide. The films consist of stacked, two-dimensional...
