With more than 6000 employees from 100 different countries, we are helping to build tomorrow’s world every day. Through top scientific research, we push back boundaries and set a course for the future – a future that you can help to shape.The EMAT research group at the Faculty of Science (University of Antwerp) is seeking to fill a PhD position on the Crystal structure evolution at surfaces of perovskite electrocatalysts during cycling under the supervision of Professor Joke Hadermann.Electrocatalytic water splitting is a promising source of green energy, but the high energy requirement of the oxygen evolution reaction necessitates the use of costly, scarce and unstable precious metal catalysts, which pose a challenge for large-scale implementation. To address this problem, this study focuses on optimizing perovskite-type oxides, which are a stable, adaptable, and low-cost alternative with good intrinsic oxygen evolution reaction activity. Specifically, we want to address the outstanding question of how the surface layers that form during operation depend on the bulk composition and how those layers contribute to the electrocatalytic properties. Our approach combines ex situ and in situ advanced transmission electron microscopy to characterize the crystal structure of individual volume elements within multiphase particles. This is combined with monitoring the electrocatalytic properties. This project will result in insights that will then be used, in collaboration with Professor Farshid Ramezanipour from the University of Louisville, US, for the further design and development of efficient and cost-effective electrocatalysts for water splitting. The role of the Ph.D. student is to perform electrocatalytic cycling with identical location TEM experiments as well as using electrochemical closed TEM cells, and determine the crystal structure evolution with a combination of TEM techniques. The student will similarly study the same materials cycled conventionally by Prof. Ramezanipour. The Ph.D. student will connect the changes in the crystal structure of the surface layers to changes in the electrocatalytic properties.Research groupEMAT is one of the leading electron microscopy centers in the world and has a vast expertise in both fundamental and applied electron microscopy. EMAT has several state of the art electron microscopes including three aberration corrected, high end FEI-Titan instruments, a dual beam FIB, an environmental SEM,… EMAT is also a pioneer in in situ 3D ED studies, as will be important in this project.
