The multi-walled carbon nanotubes (CNTs) and reduced graphene oxide (rGO) nanosheets were functionalized with 2-hydroxymethyl thiophene (CNT-f-COOTh) and 2-thiophene acetic acid (rGO-f-TAA) and grafted with poly(3-dodecylthiophene) (CNT-g-PDDT and rGO-g-PDDT) to manipulate the orientation and patterning of crystallized regioregular poly(3-hexylthiophene) (P3HT). Distinct nano-hybrid structu...
reduced graphene oxide film was synthesized on a glassy carbon electrode by electro reduction of graphene oxide powders in aqueous solution. then platinum nano particles were deposited on reduced graphene oxide film that was deposited on the glassy carbon electrode via electro reduction of platinum salt. the physical morphology of the platinum on reduced graphene oxide film was evaluated by sca...
Graphene, a two dimensional structure of carbon atoms, has been widely used as a material for gas sensing applications because of its large surface area, excellent conductivity, and ease of functionalization. This article reviews the most recent advances in graphene hybrid materials developed for gas sensing applications. In this review, synthetic approaches to fabricate graphene sensors, the n...
Artificial photosynthesis is a very attractive and a desirable way to solve the rising energy demand. In order to harvest energy directly from sunlight catalyst for oxygen reduction and evolution reaction are at the core of key renewable-energy technologies including fuel cells and water splitting. Herein, tungsten oxide-reduced graphene oxide (WO3-rGO), cobalt oxidereduced graphene oxide (Co3O...
Graphene functionalization with organics is expected to be an important step for the development of graphene-based materials with tailored electronic properties. However, its high chemical inertness makes difficult a controlled and selective covalent functionalization, and most of the works performed up to the date report electrostatic molecular adsorption or unruly functionalization. We show h...
Hybridization of distinct materials into a single nanoplatform is relevant to advance material’s properties for functional application such as biosensor platform. We report the synthesis and characterization of nanosheets of graphene oxide decorated with hybrid nanoparticles of silver-ruthenium bipyridine complex (Ag@[Ru(bpy)3] ) core and chitosan shell. Hybrid nanoparticles were first obtained...
nano-graphene oxide was synthesized by the oxidation of graphite powders. the structural nature of the nano-graphene oxide was characterized by a variety of techniques including xrd, tem, ft-ir and uv/vis. the functional groups on its basal planes and edges of nano-grahene oxide play important role in catalytic activity. the catalytic activity of nano-graphene oxide was investigated on crossed-...

Carbon nanotubes and graphene have emerged as promising nanocarbon (nC) materials in various fields. However in order to benefit from their full potential, a functionalization step is usually required. For this reason, different covalent and non-covalent derivatization methods have been developed in the last few years. In this context, we have found a new functionalization method that consists ...
