Abstract
Photoexcitation of titanium dioxide produces reactive centers capable of reducing and possibly oxidizing chemisorbed nitrogen. Activity of the photocatalysts is significantly dependent on the source of the titanium oxide and the pretreatment conditions employed. Photocatalysts with the highest activity typically consisted of anatase containing 20–40% of rutile, obtained from iron-doped anatase by a heat-pretreatment. The photocatalytic reactions of nitrogen can occur in nature on the surface of titanium containing desert sands on exposure to sunlight and thus have ecological significance as parts of the nitrogen cycle.
