Enhanced Stability Effect in Composite Polymeric Nanofibers Containing Titanium Dioxide and Carbon Nanotubes
2019/11/27 21:33:46 admin
Composite poly(acrylonitrile) nanofibers containing nanometric TiO(2) particles and multiwalled carbon nanotubes have been prepared by the electrospinning technique. The photocatalytic activity of the composite fibers was measured in the absence of contaminants as well as with acetone, or with the dye rhodamine 6G. TEM images, us well Lis FTIR measurements, showed that the presence of carbon nanotubes reduced the extent by which the polymeric matrix was degraded upon exposure to UV fight. At the same time, no adverse effect oil the ability of the photocatalyst to degrade organic molecules was observed, and in the case of rhodamine 6G. an enhanced degradation rate was observed. These apparently contradicting results are explained by I mechanism that is based on the transport of photoinduced charge carriers from the photocatalyst particles to the carbon nanotubes, which may induce a variety of effects, depending oil the degradation mechanism and reaction loci.
