主　　题：Furfural Reductive amination Ru nanoclusters Hydrogen transfer Photocatalysis 

摘      要：Selective reductive amination of carbonyl compounds with high activity is very essential for the chemical and pharmaceutical industry,but scarcely successful paradigm was reported via efficient photocatalytic ***,the ultrasmall Ru nanoclusters(~0.9 nm)were successfully fabricated over P25 support with positive charged Ru^(δ+)species at the interface.A new route was developed to achieve the furfural(FAL)to furfurylamine(FAM)by coupling the light-driven reductive amination and hydrogen transfer of ethanol over this type ***,the photocatalytic activity and selectivity are strongly dependent on the particle size and electronic structure of *** Ru^(δ+)species at the interface promote the formation of active imine intermediates;moreover,the Ru nanoclusters facilitate the separation efficiency of electrons and holes as well as accelerate the further hydrogenation of imine intermediates to product primary *** contrast Ru particles in larger nanometer size facilitate the formation of the furfuryl alcohol and excessive hydrogenation *** addition,the coupling byproducts can be effectively inhibited via the construction of *** study offers a new path to produce the primary amines from biomass-derived carbonyl compounds over hybrid semiconductor/metal-clusters photocatalyst via light-driven tandem catalytic process.
