The main focus of my research group is characterisation of catalyst materials, which uses atom probe tomography (APT) in conjunction with electron microscopy technique. The combined  chemical and structural information can help to understand mechanisms of the catalyst materials, and guide the design to achieve optimal activity and stability. I am also interested in structural materials, such as Ti alloys, used for aerospace and related applications. It focuses on the characterization of structure and chemistry, at an atomic scale, during the phase evolution, with the aim of unveiling the controversial transformations.

Catalyst surface analysed at atomic resolution

Catalyst surfaces have rarely been imaged in such detail before. And yet, every single atom can play a decisive role in catalytic activity.
Our doctorate student Weikai Xiang worked together with the Chair of Electrochemistry and Nanoscale Materials and the Chair of Industrial Chemistry. Institutes in Shanghai, China, and Didcot, UK, were also involved. The team presents their findings in the journal Nature Communications, published online on 10 January 2022.Read more..
