Understanding of the structures and roles of catalyst promoters markedly lags behind the understanding of the structures and roles of catalytic sites. Here, the authors address this challenge by incorporating a single-site promoter—tin—on a TiO2 surface to enhance the catalytic activity of various metals on the TiO2 in selective hydrogenation of nitroarenes.
