Abstract

Photocatalytic reduction of nitrite (NO2−) in an aqueous suspension of metal-free titanium(IV) oxide in the presence of ammonia (NH3) as a hole scavenger gave dinitrogen (N2), indicating that NO2− and NH3 are simultaneously removed from water as N2 at room temperature without the use of an extra reagent.
