Urea derivatives enhance the photocatalytic activity of dye-modified titanium dioxide

Photochem Photobiol Sci. 2011 Apr;10(4):623-5. doi: 10.1039/c0pp00374c. Epub 2011 Feb 4.

Abstract

Trace amounts of urea derivatives enhance the rate of nitrobenzene N3-sensitized TiO(2) photoreduction by catalyzing the proton transfer. The usually required addition of transition metal co-catalysts becomes dispensable for this visible light photocatalysis, facilitating its application in organic synthesis.
