Nitrogen Photofixation at Nanostructured Iron Titanate Films This work was supported by the Deutsche Forschungsgemeinschaft and Fonds der Chemischen Industrie. Experimental help by Dipl.-Chem. Harald Weiß is gratefully acknowledged.

Mild reducing agents such as ethanol, sodium formate, and humic acids effect the photofixation of nitrogen to ammonia and nitrate at thin films of nanostructured iron titanates. The reaction occurs in the presence of air and light, but is inhibited by the presence of carbon monoxide.
