  Heterogeneous catalysis - a surface phenomenon II: Case studies

Arpad Molnar, Hungary

Topics

  • Amorphous alloys as catalyst precursors.
  • Preparation methods: rapid quenching and mechanochemistry.
  • Characterization techniques: TPR, AES, XPS, XRD, N2O titration.
    i) Major characteristics of Cu-M (M = Ti, Zr, Hf) alloys: continuous activation, segregation, surface Cu enrichment; the behavior of Cu-Ti.
    ii) M-Mg(O) (M = Cu, Pd, Ni) catalysts in the one-step synthesis of methyl isobutyl ketone: comparative study of different metals.
  • Catalyst made by modifying solid surfaces.
  • Characterization techniques: XRD, XPS, FT-IR and Raman spectroscopy, solid-state MAS 13C and 29Si NMR, acid-base titration.
    i) Organically modified Pd-SiO2 catalysts used in the Heck and Suzuki couplings: catalyst recycling and the problem of Pd leaching.
    ii) Ordered mesoporous silica materials functionalized by sulfonic acid groups: comparative study in various test reactions, shape selective catalysis.
