Studies of Nanosized Iron-Doped TiO2 Photocatalysts by Spectroscopic Methods

摘要

Iron-doped TiO2 nanoparticles with iron content in the range of 0.005 400 nm) at 25 A degrees C. Correlations were made between EPR and photocatalytic activity results. The specific surface area S data allowed us to deduce that the isolated Fe(III) centers were responsible for the photomineralisation of oxalic acid, while the Fe(III) ferromagnetic aggregates decreased the total efficiency of the system.
