creating water soluble luminescent graphene quantum dots via exfoliating and disintegrating carbon nanotubes and graphite

Synthesis, Characterization and Applications of Graphene

Graphene quantum dots (GQDs) represent unique zero-dimensional (0D) carbon materials with the lateral size below 100 nm. It possesses similar characteristics to graphene including large surface area, high electronic mobility, non-toxicity and

Production and processing of graphene and 2d crystals

Graphene oxide quantum dots (GOQDs) have been produced via hydrothermal377 and solvothermal378 methods having lateral sizes -10 nm377 and in the ~5 - 25 nm range378, respectively. Another route to produce GOQDs exploits the hydrazine hydrate reduction of small GO sheets with their surface passivated by oligomeric polyethylene glycol (PEG)379.

Supercritical Fluid‐Facilitated Exfoliation and Processing of

ScCO 2 is a well‐known SCF with a readily accessible critical point (Table 2).It has been used for exfoliating 2D crystals 18 because it is cheap, abundant, nontoxic, nonflammable, recyclable, and environmentally friendly. ScCO 2 can provide a repulsive free energy barrier to inhibit exfoliated sheets from re‐stacking, affording good stability while maintained in a supercritical state.

Abstract: Green fluorescent carbon quantum dots (G-CQDs) were synthesized from corn starch and oxalic acid via an ethanol solvothermal method. The morphology, composition and structure of G-CQDs were analyzed using transmission electron microscopy (TEM), Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy.

Synthesis of highly fluorescent and water soluble

Fluorescent graphene quantum dots (GQDs) are nanomaterials which possess unique properties that show great potential in different applications. In this work, GQDs were synthesized using graphene oxide (GO) as precursor via thermal treatment at high temperature. The obtained GQDs were highly fluorescent and were suitable for the determination of heavy metal ions. X-ray diffraction, FTIR

Here we report on a first principle, computational study focusing on water confined between prototypical nonpolar substrates, i.e., single-wall carbon nanotubes and graphene sheets, 1-2.5 nm apart. The results of our molecular dynamics simulations show the presence of a thin, interfacial liquid layer (~5 ? whose microscopic structure and thickness are independent of the distance between
