Photochemical route for synthesizing atomically dispersed palladium catalysts

Lightly dispersed palladium Catalysts made from atomically dispersed metal atoms on oxide supports can exhibit very high per atom activity. However, the low loadings needed to prevent metal particle formation can limit overall performance. Liu et al. stably decorated titanium oxide nanosheets with relatively high loadings of single palladium atoms by reducing the ions with ultraviolet light and ethylene glycol. These catalysts cleaved H 2 into atoms and were highly effective for hydrogenating alkenes and aldehydes. Science , this issue p. 797
