X-ray and neutron reflectometry
The focus of our research is the application of modern structural techniques in the study of adsorption processes and reactions at interfaces, particularly at electrode surfaces. Our research interests span a wide range, from understanding biophysical processes through to the design and evaluation of new catalytic materials. Our current interests include investigating lipid monolayers and bilayers and their interactions with peptides, using x-ray and neutron reflectivity and electrochemical infrared spectroscopy. We also study electrocatalytic reactions, such as oxygen reduction and nitrate reduction, using a range of nanoparticle-based catalysts synthesised in our laboratory. Collaborating with colleagues, we apply electrochemical tools to sensing applications.
Classical electrochemical methodology is combined with modern in situ techniques to determine structure of our tailored surfaces and catalysts as well as reaction mechanisms. The underlying theme of our work is to understand interfacial processes at a fundamental level, with a view toward exploiting this information in the development of new materials, sensors or catalysts.
