Photocatalytic reduction of dinitrogen to ammonia over noble-metal-loaded TiO2
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

Improvement of photoelectrochemical hydrogen generation by surface modification of p-type silicon semiconductor photocathodes
TL;DR: In this article, the improvement of H/sub 2/ evolution from two different types of catalytic p-type photocathode surfaces has been examined, and a comparison of the naked p-Si, the simply platinized, and the (PQ/sup 2 +//sup ///sup +/.)sub n/.nPt(0))/sub surf/ system compared to the same surface directly platinised confirm an important difference in the mechanism of H /sub 2 / evolution catalysis for the two surface catalyst systems.
