Description

Iron(III)-doped TiO2 nanopowders with mean particle size of 5070 nm have been synthesized by the plasma oxidative pyrolysis method having advantages of full crystallization, controlled dopant concentration and uniform dopant distribution. Under UV irradiation, the photocatalytic reactivity of the undoped TiO2 was much higher than the doped TiO2, suggesting that iron doping in TiO2 with mean particle size of approximately 60 nm was detrimental to the photocatalytic decomposition of methyl orange in water. Whereas, under visible light irradiation, the iron-doped TiO2 with moderate iron doping concentration showed higher photocatalytic activity than the undoped TiO2 although the reactivity of those having both low and high doping concentrations was lower.
