Prof. Bowker leads the Heterogeneous Catalysis and Surface Science group in Cardiff, consisting of nine academic members of staff and 70 researchers. He founded the Wolfson Nanoscience Laboratory at Cardiff in 2006 and is Deputy Director of the recently established Cardiff Catalysis Institute. His research has focused on surface structure/reactivity and catalysis, ranging from theoretical studies of the effect of sintering on product yields, to selective oxidation catalysis on oxide nanomaterials, to studies of adsorption on well-defined surfaces. He has used STM for 20 years to study various aspects of surface structure and reactivity, pioneering the use of high temperature, atomic resolution STM in this field. The group continues to focus on aspects of surface science and catalysis, now extending to include nanofabrication, nanoengineering and bio-surface interactions.

- Catalysis, particularly selective oxidation and photocatalysis, the latter mainly for hydrogen production.
- Fundamental research into the preparation and characteristics of catalysts used for environmental protection, especially for the removal of pollutants from cars
- Nanofabrication and nanoengineering
- Nanofabrication of model catalysts, consisting of nanoparticles anchored to oxide surfaces, and imaging them with scanning tunnelling microscopy
- Investigation of the atomic-scale structure and reactivity of crystalline surfaces
The work of my group is aimed at gaining an understanding aspects of heterogeneous catalysis. This especially involves aspects of the structure and reactivity of anchored nanoparticles, that is, small metal particles (e.g. Au, Pd, Pt) bound to inorganic surfaces. This is of great importance in relation to the understanding of nanostructures generally, but it is also of practical relevance - for example, we work on iron molybdate catalysts for the selective oxidation of methanol to formaldehyde, and on the production of new fuels (especially hydrogen) using photocatalysis.
We use a wide range of experimental methods and have recently made significant new investments in equipment. We have the ability to image surfaces and nanoparticles at the atomic scale using scanning tunnelling microscopy (STM) and examples of this type of work are shown below. Members of the group regularly give presentations at scientific meetings in the UK and abroad.
