INVESTIGATION OS SMSI CATALYSTS USING DEUTERIUM EXCHANGE AS A MECHANISTIC PROBE

Objective


A new method for selective hydrogenation involving molecular hydrogen has been developed. This has implications in many other catalytic systems (eg methanol synthesis on copper based catalysts).

Sensitive chemical probes have been used to study the mechanisms involved at catalytic surfaces.
Investigation of the titania- and vanadia-supported platinium and palladium catalysts which exhibit strong metal-support interaction (SMSI). In the first instance the catalysts would be examined for their adsorption capacity with CO and N2. The skeletal rearrangement of selected alkanes on these catalysts would be studied at the same time. In order to unveil the different classes of catalytic site on these catalysts, the exchange reaction of alkanes with deuterium would be examined on them. It is proposed to advance them to a determination of the mechanisms of some key skeletal
rearrangement processes for alkanes on Pt and on Pd at the higher temperatures using the SMSI catalysts and employing D2 as a
mechanistic probe.
