TLDR
The photocatalytic reduction of dinitrogen to ammonia is influenced by the nature and amount of metal loading on TiO2 and the optimum metal content varies depending on the nature of the metal as mentioned in this paper.Abstract:
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 MH bond strength is established (low bond strength gives rise to low ammonia yield).read more
