Researchers in Japan report that a commercially available TiO 2 with a large number of surface oxygen vacancies, when photo-irradiated by UV light in pure water with nitrogen—successfully produces ammonia (NH 3 ). As a result of this, NH 3 is produced from water and N 2 under ambient conditions by using sunlight as energy source.
