Research Group

Parkinson Group My research group utilizes a comprehensive surface science approach to study the physics and chemistry of metal oxide surfaces, and heterogeneous catalysis on sub-nano metal particles supported on metal oxide surfaces. Recently, we have been working with the (001) of magnetite (see below) and the (012) surface of Hematite. Going forward, we aim to combine our successful STM work with data from our new state of the art Machine for Reactivity Studies (The Mrs.) see right.

Surface Science Report / Habilitation

My review of Iron oxide surface science, also my habilitation thesis, was recently published in Surface Science Reports. It can be downloaded from the following link:

START Prize 2015

In June 2015 I was awarded the FWF START prize, which grants me 1.2 million euros for my research for the next 6 years.June has been a good month for me!

Laufbahnstelle

In June 2015 I became a Tenure Track Assistant Professor at the TU Wien. I'm delighted and grateful for the opportunity to continue working in the world-class research environment in the surface science group at the IAP!

The Magnetite (001) Adatom Template

In recent years my group has worked to understand the remarkable adatom templating property of the Fe3O4(001) surface. Here, a unusual surface reconstruction stabilizes metal adatoms up to 700 K, an ideal model system for studies of cluster nucleation and growth, and single atom catalysis.

The Machine for Reactivity Studies

The Machine for Reactivity Studies, otherwise known as The Mrs., is finally up and running at the IAP. Isn't she beautiful?! We are all excited to combine this state of the art surface chemistry setup with our STM studies. The first question… Can our single atoms really be catalytically active?. With the help of the Mrs., we will soon know. Thanks to Jiri Pavelec for all his hard work on this!
