Au(I) complex-titania hybrid photocatalyst for hydrogen production

Integration of TiO2 and an Au(I) complex containing a thiocoumarin moiety results in a very efficient photocatalyst for the generation of H2. The molecular structure of the complex is preserved under photoreaction due to the strong Au(I)-S bond. The Au(I) complex plays a determinant role in the phot...
