Topic: “Phosphines at the boundary of homogeneous and heterogeneous catalysis”

Her research focuses on:

  • homogeneous catalysis
  • heterogeneous catalyst
  • ligand-decorated nanoparticles
  • single-atom catalyst


Significant research efforts have recently been dedicated to the heterogenization of homogeneous catalysts, blurring the boundaries between homo- and heterogeneous catalysis. One promising approach in this context involves the dilution of a d-block metal with an element from the p-block and the subsequent formation of d-metal/p-block element phase, such as a metal phosphide.[1] The dilution of the metal matrix results in the formation of highly defined and uniformly distributed active sites, which are often coordinatively unsaturated “frustrated single-sites”.[2] This analogy to homogenous molecular catalysts is the reason for d-metal/p-block element phases being referred to as heterogenized catalysts, which have the potential to combine the high activity of homogeneous and enhanced stability of heterogeneous catalysts.
Within the realm of heterogenized d-metal/p-block element catalysts, phosphorus has been one of the p-block elements of choice due to its versatile coordination chemistry and interesting reactivity patterns.[3] This property allows for a facile electronic and steric modulation of metal centers, not only in homogeneous but also in heterogenized catalysts. The advantages of phosphorus laid also the foundation for investigating Pd3P, supported on silica as a catalyst for Heck coupling reactions.[4]
