Towards enhanced photocatalysis: Iron

Morphological, electronic and crystal structure as well as magnetic properties of pure and Fe-incorporated titania nanoparticles are investigated in their as-made and calcined states (three-hour calcination in air at 400 C). Results indicate that Fe incorporation leads to a decrease in the band gap energy and an expansion of the anatase unit cell volume.
