This paper reports cadmium sulphide nanoparticles-(CdS NPs)-graphene nanocomposite (CdS-Graphene), prepared by a simple method, in which CdS NPs were anchored/decorated successfully onto graphene sheets. The as-synthesized nanocomposite was characterized using standard characterization techniques. A combination of CdS NPs with the optimal amount of two-dimensional graphene sheets had a profound...
The best electrode performance of metal oxide-graphene nanocomposite material for lithium secondary batteries can be achieved by using the colloidal mixture of layered CoO2 and graphene nanosheets as a precursor. The intervention of layered CoO2 nanosheets in-between graphene nanosheets is fairly effective in optimizing the pore and composite structures of the Co3O4-graphene nanocomposite and a...
a feasible and fast method to fabricate hydrogen peroxide sensor was investigated by graphene-manganase nanocomposite carbone paste electrode. in the present work, in first step, the graphene was synthesized by chemical method and in second step, manganese oxide nanoparticle was doped on graphene. graphene-manganase nanocomposite was characterized by ftir and sem. the nanocomposite shows a high...
we report the synthesized and preparation of graphene oxide (go) nanocomposite functionalized with polyvinyl alcohol (pva) with different concentration of graphene oxide 0, 1, 1.5, 2, 2.5, 3, 3.5 and 4% weight. this synthesized confirmed by ft-ir. the electrical conductivity of the all nanocomposite was measured at 25°c for all samples and the resulted showed electrical conductivity was increas...

A novel nanocomposite has been developed using extracted cellulose from marine algae coated with conductive polypyrrole and graphene nanoplateletes. The nanocomposite fabricated via in situ polymerization was used as an electrode for a supercapacitor device. The nanocomposite material has been electrochemically characterized using cyclic voltammetry to test its potential to super-capacitive beh...
SnO2 nanoparticles were dispersed on graphene nanosheets through a solvothermal approach using ethylene glycol as the solvent. The uniform distribution of SnO2 nanoparticles on graphene nanosheets has been confirmed by scanning electron microscopy and transmission electron microscopy. The particle size of SnO2 was determined to be around 5 nm. The as-synthesized SnO2/graphene nanocomposite exhi...
Highly sensitive graphene-based gas sensors can be made using large-area single layer graphene, but the cost of large-area pure graphene is high, making the simpler reduced graphene oxide (rGO) an attractive alternative. To use rGO for gas sensing, however, require a high active surface area and slightly different approach is needed. Here, we report on a simple method to produce kaolin-graphene...

The interfacial effect on the structural, electronic and optical properties of a hybrid triazine-based graphitic carbon nitride and graphene nanocomposite is calculated using the first-principles method. It reveals the favorable stacking pattern utilizing the ab initio thermodynamics approach. The electronic band structure presents that the high carrier mobility is maintained in a hybrid g-CN/G...
