Develop titanium-mesh electrodes for the conversion of CO₂ to formate

During this third-year internship, you will work on a topical issue within the field of sustainable chemical technology: how can carbon dioxide (CO₂) be converted into useful raw materials? You will investigate titanium-mesh electrodes modified with bismuth catalysts based on zeolitic imidazolate frameworks (ZIF). Using these electrodes, you will explore how CO₂ can be converted—powered by renewable electricity—into formate, a product used in various applications, including the chemical industry and road de-icing.You will be part of the Centre of Expertise MNEXT, where you will focus on the development, characterization, and electrochemical evaluation of these electrodes. The internship begins in February 2027. Applications will be reviewed on an ongoing basis until a suitable candidate is found.

You will support the development and testing of titanium-mesh electrodes for the electrochemical conversion of CO₂ into formate. In this process, you will investigate how the electrode composition, the properties of the catalyst, and the chosen electrochemical conditions influence performance.

A key part of the assignment involves preparing and modifying titanium-mesh electrodes using bismuth-based catalysts derived from ZIF (zeolitic imidazolate framework) materials. You will characterize these electrodes using techniques such as scanning electron microscopy (SEM) and X-ray diffraction (XRD). SEM will be used to examine the surface structure of the material, while XRD will provide information regarding its crystal structure.

Furthermore, you will conduct electrochemical experiments using an H-cell configuration. This will involve employing various measurement techniques, including cyclic voltammetry (CV), linear sweep voltammetry (LSV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS). You will investigate factors such as the applied potential, the composition of the electrolyte, and the properties of the catalyst.

You will evaluate the performance of the electrodes based on metrics including current density, Faradaic efficiency, formate production, and stability. Additionally, you will analyze the experimental results and identify opportunities to enhance the efficiency and durability of the electrodes. You will document your work from a technical perspective and contribute to the reporting of the research findings.

CO₂ electrolysis presents several challenges. The electrode must maintain sufficient catalytic activity while minimizing competing reactions—such as hydrogen evolution—as much as possible. Factors such as mass transport, the infiltration of the electrode by liquid, and long-term stability can also influence performance.

This assignment is a good fit if you have a background in chemistry, chemical engineering, or a related field, and an interest in electrochemistry, laboratory work, and CO₂ conversion.
