Palladium nanoparticles for catalysis


Why palladium?
Palladium is one of the most versatile elements from the platinum group metals. Palladium nanoparticles are extensively used as catalysts in a number of industrially relevant reactions. In particular, palladium is recognized as the preferred catalyst for selective hydrogenation of hydrocarbons (e.g. hydrogenation of alkynes in the alkyne/alkene mixtures), selective oxidation of alcohols and methane combustion.

Where is the room for research?
In reaction conditions, palladium nanoparticles may undergo phase transitions to palladium hydrides, carbides or oxides. Formation of these phases can dramatically change the catalytic activity and selectivity of the catalysts. Despite numerous theoretical and experimental investigation the structure-reactivity relationships and the mechanistic understanding of the catalytic reaction on the surface of palladium nanoparticles is still debated. Therefore, investigation of these phase transitions and their effect on the catalytic properties is the problem of both practical importance and fundamental scientific interest.
What problems do we solve?
We investigate the evolution of atomic and electronic structure of palladium-based catalysts by in situ, operando and time-resolved X-ray absorption spectroscopy and X-ray diffraction. Term "operando" means that we perform our measurements under industrially relevant conditions, when our material is working as catalysts for a model reaction (e.g. hydrogenation of acetylene or oxidation of alcohols). We have proposed an approach that allows to discriminate hydride, carbide and oxide phases, as well as their distribution in the volume of the nanoparticles, by simultaneous application of XRPD, EXAFS and XANES. In addition, new and original approaches for XANES analysis in combination with theoretical simulations have been developed.
