Nickel-substituted cobalt ferrite–reduced graphene oxide (NCF-RGO) composite was synthesized using a facile one-pot chemical coprecipitation method. The addition of (GO) leads to the decrease in size NCF nanoparticles (< 10 nm) present nanocomposite, which plays role controlling their magnetic and dielectric properties. Nickel with lower ionic radius compared cobalt, its substitution along inco...

A facile approach of making scalable nanocomposite and electro-patterned films using graphene oxide (GO) and poly(N-vinylcarbazole) (PVK) is reported. The method involves the layering of polystyrene colloidal templates, electrodeposition of the composite film on template array, and finally removal of the sacrificial templates to reveal the patterned GO-PVK arrays.

Carbon and noble metal nanomaterials exhibit unique properties that have been explored over the last few decades for developing electrochemical sensors and biosensors. Hybridization of nanometals to carbon nanomaterials such as graphene or carbon nanotubes produces a synergistic effect on the electrocatalytic activity when compared to either material alone. However, to date there are no compara...

   In this work, magnetic graphene oxide (MGO) was prepared by in situ synthesis of magnetite nanoparticles in the presence of graphene oxide (GO). The prepared nanocomposite was characterized by applying scanning electron microscopy (SEM), X-ray diffraction (XRD, Fourier transform infrared spectroscopy (FTIR) and vibrating sample magnetometer (VSM). MGO was applied as an ...

In this work, a self-electrochemiluminous graphene oxide-capped Au@L012 nanocomposite was prepared as the label at carcinoembryonic (CEA) antibody to detect attomole CEA antigen. To maximize the luminescence intensity, L012 molecules (luminol analogue) were linked with poly(diallyldimethylammonium chloride) (PDDA) to form positive charged PDDA&L012 pairs, which were modified on negative charged...

Graphene-based nanocomposites have been demonstrated to be promising high-capacity anodes for lithium ion batteries to satisfy the ever-growing demands for higher capacity, longer cycle life and better high-rate performance. Synergetic effects between graphene and the introduced second-phase component are generally observed. In this feature review article, we will focus on the recent work on fo...

Abstract In this work, Fe3O4-graphene oxide nanocomposite (GO-Fe3O4) was prepared as effective absorbent for magnetic solid phase extraction (MSPE) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (Alizarin red S) and flame atomic absorption spectrometry (FAAS). The   GO-Fe3O4 was characterized by scanni...

We demonstrated the replacement of the Pt catalyst normally used in the counter electrode of a dye-sensitized solar cell (DSSC) by a nanocomposite of dry spun carbon multi-walled nanotube (MWNT) sheets with graphene flakes (Gr-F). The effectiveness of this counter electrode on the reduction of the triiodide in the iodide/triiodide redox (I(-)/I(3)(-)) redox reaction was studied in parallel wit...

Different nanocomposites between reduced graphene oxide (rGO) and Ni(OH)2 nanoparticles were synthesized through modifications in the polyol method (starting from graphene oxide (GO) dispersion in ethylene glycol and nickel acetate), processed as thin films through the liquid-liquid interfacial route, homogeneously deposited over transparent electrodes and spectroscopically, microscopically and...

The petroleum compounds were photocatalytically remediated from water using graphene (G)titanium oxide (TiO2) nanocomposite material in visible light radiation. The G-TiO2 nanocomposite was synthesized using sol-gel technique, and its structural & morphological properties were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), part...
