Catalytic Activity of Gold Nanoparticles Immobilized Onto Single-Walled Carbon Nanotubes Using N,N'-Bis(2-pyridylmethyl)-2-Hydroxyethylamine.

Au NPs were immobilized onto the surface of single-walled carbon nanotubes (SWCNTs) via covalent functionalization of SWCNTs using N,N'-bis(2-pyridylmethyl)-2-hydroxyethylamine (BPMEA-OH), which was confirmed by Fourier transform infrared spectroscopy. The morphology of the resulting SWCNTs/Au NPs composites was observed by transmission electron microscopy and field emission scanning electron microscopy with X-ray microanalysis. The catalytic activity of SWCNT/Au NPs was investigated by UV-Vis absorption measurements.
