    The synthesis and characterization of four organometallic gold(I) complexes containing different water soluble phosphanes (TPPTS, PTA and DAPTA) and chromophoric units (4-pyridylethynyl and propargyloxycoumarin) is here ...
  • Magnetite-supported palladium single-atoms do not catalyse the hydrogenation of alkenes but small clusters do 

    Rosell, Marta D.; Caparrós, Francisco J.; Angurell Purroy, Inmaculada; Müller Jevenois, Guillermo; Llorca Piqué, Jordi; Seco García, Miquel Angel; Rosell, Oriol (2016-01-01)
    Article
    Restricted access - publisher's policy
    The activity of supported noble metal catalysts strongly depends on the particle size. The ultimate small-size limit is the single-atom catalyst (SAC), which maximizes the catalytic efficiency in the majority of the examples. ...
