PHOTOCATALYTIC DEGRADATION OF TRICHLOROETHYLENE OVER SILVER NANOPARTICLES SUPPORTED ON TIO2
The photocatalytic degradation of trichloroethylene over Ag nanoparticles supported on TiO2 was studied. The photocatalysts were obtained by impregnation of Ag colloids on TiO2. They were characterized by XPS, TEM and UV-vis. Ag° nanoparticles were obtained with diameters between 2.0-3.2 nm. The pho...
