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