Effect of carbon nanotubes and carbon nanotubes/gold nanoparticles composite on the photocatalytic activity of TiO2 and TiO2-SiO2
A carbon nanotube (CNT)/gold nanoparticle (NP) nanocomposite was synthesized by simultaneously reducing the Au ions and depositing Au NPs on the surface of a CNT. The functional groups were investigated with Fourier transform infrared spectra. From the Raman spectra, the D-band and G-band of the CNT were identified. The deposition of nanometer-sized Au NPs on the CNT sites was observed by transmission electron microscopy.
