Development of Gold Phosphorus Supported Carbon Nanocomposites

Gold-carbon nanotube nanocomposites: synthesis and applications

Nanocomposites are combinations of nanomaterials with other molecules or nanoscaled materials, such as nanoparticles or nanotubes. In general, these novel nanocomposites have different physical and chemical properties from the constituent particles or wires, and will thus allow new kinds of applications. Among these nanocomposites, gold-carbon nanotube (AuCNT) composites are of particular inter...

Development of Noncytotoxic Chitosan–Gold Nanocomposites as Efficient Antibacterial Materials

This work describes the synthesis and characterization of noncytotoxic nanocomposites either colloidal or as films exhibiting high antibacterial activity. The biocompatible and biodegradable polymer chitosan was used as reducing and stabilizing agent for the synthesis of gold nanoparticles embedded in it. Herein, for the first time, three different chitosan grades varying in the average molecul...

Oxygen reduction catalyzed by gold nanoclusters supported on carbon nanosheets.

Nanocomposites based on p-mercaptobenzoic acid-functionalized gold nanoclusters, Au102(p-MBA)44, and porous carbon nanosheets have been fabricated and employed as highly efficient electrocatalysts for oxygen reduction reaction (ORR). Au102(p-MBA)44 clusters were synthesized via a wet chemical approach, and loaded onto carbon nanosheets. Pyrolysis at elevated temperatures led to effective remova...

Synthesis and Characterization of Polyaniline/Gold Nanocomposites

Conductive polymers are a new class of materials, which exhibit highly reversible redox behavior and unusual combination of properties of metals and plastics. The conductivity of a polymer can be increased several-fold by doping it with a suitable dopant. Doping plays a very important role to convert the polymer into conductive form. In this work an attempt has been made to synthesize polyanili...
