PHOTOCATALYTIC REACTIONS OF AZIDE IONS ON PLATINIZED TITANIUM DIOXIDE POWDERS IN SOLUTIONS.

Article abstract of DOI:10.1246/bcsj.57.3066

Ammonia was formed photocatalytically from an aqueous solution of azide ion by using illuminated Pt/TiO//2 semiconductor powder. The reaction products, NH//3, N//2, and small amounts of N//2O and NO//3** minus , were detected. Hydrogen, O//2 and N//2H//4 were not formed in the primary reaction products. From these results, together with photoelectrochemical measurements, a mechanism of the ammonia formation from azide ion and water is presented.
