Prof. Aliaksandr Bandarenka
Research Field
We conduct research in the area of the physics of energy conversion and storage. The main topics include the design and implementation of functional materials and a better understanding and characterization of electrified interfaces. The material design is based on a bottom-up approach using input from electrochemical surface science and starting from model surfaces.

- Computational fast screening of core-shell nanoparticles for oxygen reduction reaction in fuel cells
Electrocatalysis technologies, including PEM fuel cells, can help to shape a sustainable energy future in which PEM fuel cells provide versatile stationary and portable power solutions. However, one key factor limiting their widespread commercialization are high costs for large platinum (Pt) loadings, which are required to catalyze the sluggish oxygen reduction reaction (ORR) at the fuel cell cathode. Thus, enhancing the catalyst activity with respect to the Pt mass is of great interest.
In this MSc work, we capitalize on data-driven design to propose new Pt catalysts with enhanced mass activities toward the ORR. We link experimental data with results from density functional theory (DFT) on Pt-based ORR catalysts to build a computational model which predicts mass activities.
The thesis will focus on generalizing a developed method based on generalized coordination numbers for high-throughput screenings to tailor electrocatalyst shapes and sizes toward optimized mass activities. In particular, we want to explore core-shell nanoparticles. In core-shell nanoparticles, the catalysis is driven on active Pt shells, but cheaper and more abundant metals at the core limit the precious Pt loading.

- Top-down approach for the synthesis of shape controlled nanoparticles
- The thesis focuses on the facile synthesis of nanoparticles (NPs) by electrochemical erosion of different materials. NP can be immobilized on a support for applications in electro- and heterogeneous catalysis. Our unique approach involves applying an alternating voltage to a metal substrate placed in an electrolyte. The “green” method uses no further chemicals and allows controlling shape and size of the NPs adjusting parameters such as applied potential, frequency and electrolyte composition. Different characterization techniques such as TGA, XPS, XRD, SEM etc. will be used for the investigation of prepared materials and performance tests will be conducted. The contact persons are Dr. Elena Gubanova (elena.gubanova@tum.de) and Christian Schott (christian.schott@tum.de).
