Reductive alkylation of three graphite starting materials G(flake), G(powder), and G(spherical) reveals pronounced differences in the obtained covalently functionalized graphene with respect to the degree of functionalization, exfoliation efficiency and product homogeneity, as demonstrated by statistical Raman microscopy (SRM), TGA/MS, IR-spectroscopy and solubility behavior.

A novel, simple, sensitive and effective method has been developed for preconcentration of Ni (II) on functionalized Graphene oxide with covalently linked porphyrin (GO–H2NP) solid-phase extraction adsorbent. The stability of a chemical (GO–H2NP), especially in concentrated hydrochloric acid, was then used as a recycling and pre-concentration reagent. The method is based on selective chelation ...

Between the sheets: Sodium-ion batteries are an attractive, low-cost alternative to lithium-ion batteries. Nitrogen-doped porous carbon sheets are prepared by chemical activation of polypyrrole-functionalized graphene sheets. When using the sheets as anode material in sodium-ion batteries, their unique compositional and structural features result in high reversible capacity, good cycling stabil...

A bottom-up approach for preparing multifunctional graphene-based materials noncovalently functionalized with CL reagents with aromatic rings such as N-(aminobutyl)-N-(ethylisoluminol) (ABEI), luminol and isoluminol is reported. The as-prepared nanocomposites exhibit good CL activity, which may find future applications in analytical, electrochemical and biomedical fields.

A organic-solution-processable functionalized-graphene (SPFGraphene) material has been studied on pre-concentration and determination of trace Mo(II)ions. In this process, the effects of pH solution, elution conditions on pre-concentration of trace Mo(II) were studied and the effect of interfering ions was also investigated. A selective method for the fast determination of trace amounts of Mo (...

The new magnetic amine-functionalized graphene oxide (Fe3O4-GO-NH2) nanocatalyst was prepared through the reaction of 3-aminopropyltriethoxysilane (APTES) with magnetic graphene oxide (Fe3O4-GO). It was characterized by XRD, TEM, SEM, FT-IR and EDX techniques. The intrinsic carboxylic acids on the edges of Fe3O4-GO alo...

Carbon nanofibers encapsulating Si nanoparticles (CNFs/SiNPs) were prepared via an electrospinning method and chemically functionalized with 3-aminopropyltriethoxysilane (APS) to be grafted onto graphene oxide (GO). As a result, the thin and flexible GO, which exhibits a negative charge in aqueous solution, fully wrapped around the APS-functionalized CNFs with a positive surface charge via elec...

Polypropylene (PP) is a general-purpose plastic, but some applications are constrained by its high flammability. Thus, flame retardant PP is urgently demanded. In this article, intumescent flame retardant PP (IFRPP) composites with enhanced fire safety were prepared using 1-oxo-4-hydroxymethyl-2,6,7-trioxa-1-phosphabicyclo [2.2.2] octane (PEPA) functionalized graphene oxide (PGO) as synergist. ...

Brightly luminescent, atomically precise subnanometer clusters of silver protected by glutathione were covalently functionalized by solution phase thiolated graphene using ligand exchange. A hybrid molecule was formed, which was obtained in a nearly pure form by phase transfer from the aqueous to the organic phase. The resulting hybrid exhibited properties of both of these nanoscale materials. ...
