Abstract

Trace amounts of urea derivatives enhance the rate of nitrobenzene N3-sensitized TiO2 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.
