Atomic structure

We use high pressure scanning tunnelling microscopy (HPSTM) to probe the atomic structure of model catalysts in the presence of reactant gases like CO, CO2, and CH3OH. 

The micro-reactor

Bridging the material and pressure gaps

We plan to extend the capacity of the currently existing techniques to be operable in the presence of 1 bar of gas and in (electrified) liquids. Moreover, we would like our techniques to probe insulating materials such as oxides which are also essential in chemical processes.

Reactions on surfaces

Following surface reactions

We use two surface-sensitive spectroscopy techniques, ambient pressure photoelectron spectroscopy (APXPS) and polarisation modulated infrared reflection absorption spectroscopy (PM-IRRAS), to monitor the changes in the chemical nature of model catalysts and adsorbed species.
