Photocatalytic reduction of dinitrogen to ammonia over noble-metal-loaded TiO<inf>2</inf>

The photocatalytic reduction of dinitrogen to ammonia is influenced by the nature and amount of metal loading on TiO2. The optimum metal content varies depending on the nature of the metal. A correlation between the ammonia yield and the intermediary M-H bond strength is established (low bond strength gives rise to low ammonia yield).
