Effects of various hydrogenated temperatures on photocatalytic activity of mesoporous titanium dioxide

TL;DR: In this article, the structural properties of H-TiO2 and its effects on photogenerated charges are investigated, and it is shown that H- TiO2 treated at high temperature can cause the formation of less photoactive rutile phase and agglomeration that leads to the inhibition of their photocatalytic activity.

TL;DR: In this paper , the formation of nanoporous, wet-chemically produced sodium titanate films onto microspherical substrates of varying composition was investigated. But, the results showed that excessive oxygen content (flame-spheroidised anatase and rutile powders) resulted in inhibition of titanate formation, apart from the top few nanometres of the surface.
