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.
