HiWi Position - Developing Single-Atom Catalysts for Electrochemical H2O2 Synthesis

Tasks and goals: In the project (Photo)electrochemical production of H2O2 for H2O2-fueled adaptive processes within the Cluster of Excellence Living, Adaptive, and Energy-autonomous Materials Systems (livMatS), we concentrate on developing efficient single-atom catalysts (SAC) for H2O2 production. We utilize electrochemical techniques as a clean and sustainable approach, serving as a promising successor to the traditional anthraquinone method, which involves complex chemical processes with environmental drawbacks.

SACs are a class of catalysts where individual metal atoms are dispersed on a support material. These catalysts offer high efficiency and selectivity due to precise control over the active sites, leading to enhanced catalytic performance in various chemical reactions. By leveraging the power of electrochemistry and cutting-edge catalyst design, we aim to produce decentralized H2O2 efficiently and sustainably, with minimal environmental impact, as a fuel for driving adaptive material processes.

As a student research assistant in this project, you will have the opportunity to delve into the synthesis of SAC and acquire fundamental knowledge of electrochemical techniques. You will also gain hands-on experience in several materials characterization techniques such as scanning electron microscopy and Raman spectroscopy.   


Recommended prerequisites: While experience in synthesis and knowledge of electrochemistry is preferred, we welcome enthusiastic students who are keen to explore pioneer research. Following a thorough introduction, we anticipate independent work with proactive thinking, precision, and motivation. Proficiency and confidence in laboratory work are essential. Candidates for this student job should possess strong communication skills and the ability to collaborate effectively within a group setting.
