tio nanoparticles by high energy ball mill
1. Introduction
Iron doped TiO 2 nanoparticles were prepared by ball milling of TiO 2 powders (TiO 2 P25) in a highenergy ball mill in the presence of fine FeCl 3 powder using Al 2 O 3 balls. The slurry was prepared by mixing TiO 2 powder and iron chloride in DI water in 1 : 5 ratio for 120 min at 1200 rpm. After 30 min the Ag powder was added in the slurry for the removal of unreacted FeCl 3.
