The group "Solid Molecular Catalysts" is always looking for new talented students. Feel free to contact Dr. Anna Katharina Beine for this purpose.
Inquiries should include a motivation letter as well as a CV and a grade summary.
Specific projects for which we are currently looking for collaborators are listed below:
With heterogeneous catalysis and materials development as our core competence, we address global challenges by developing sustainable chemical reactions and processes. Our research focuses on the development of materials for the chemical conversion of renewable energy and carbon sources. This includes, for example, electrochemical water splitting, but also the conversion of renewable raw materials such as biomass. We are particularly interested in understanding the mechanisms and compositions of the developed catalysts in order to further improve them or use them in other reactions. In this way, we are contributing to shaping a greener future.
Our current research focuses are:
Hydroformylation remains one of the largest homogeneously catalyzed reactions in industrial chemistry. Together with our project partners at MPI-CEC and Hamburg University, we are developing new homogeneous Co-based catalysts to successfully catalyze the reaction. In addition to the optimization of the process parameters, the immobilization of the catalysts on suitable heterogeneous support materials is being investigated.
In times of climate change and diminishing fossil resources, the transition to renewable raw materials such as lignocellulose is essential. In this project, the hydrolytic hydrogenation of hemicellulose to xylitol is investigated. Xylitol is both a widely used sugar substitute and an important platform chemical for biorefinery. In a tandem reaction, the polysaccharide is first depolymerized to xylose by acid-catalyzed hydrolysis, followed by metal-catalyzed hydrogenation to xylitol. In this context, Brønsted acidic heteropolyacids (HPAs) in combination with Ru/C were shown to be an efficient catalyst system. Although the HPAs exhibit excellent catalytic activity, their good solubility in water and various organic solvents makes their recycling difficult. To address this challenge, the immobilization of HPAs on heterogeneous supports is investigated. The solid acid catalysts prepared are characterized in depth and tested in the reaction. The construction of a suitable reactor is planned for the investigation of long-term stability.
The oxygen evolution at the anode of the electrochemical water splitting reaction has already been extensively studied in the group.[2-4] Advanced studies are planned for the future.
In addition, the electrochemical conversion of biobased molecules is in the focus of research. Here, conversions along the value chain of hemicellulose are to be investigated in particular in 200% cells. HPAs are used as catalysts, either as electrolytes or immobilized onto the conducting electrode.
In addition to the already known biorefinery conversions and products, other new reaction pathways are opening up, leading to products that can be used, for example, in the polymer industry, as solvents or fuel additives. Thus, starting from substrates such as xylose or 1,4-anhydroxylitol, access to difromylxylose, tetrahydrofuran or methyltetrahydrofuran and ethylene-glycol-glycerol-ether is made possible.
Formaldehyde is a bulk chemical and serves as substrate for the production of products such as polymers and paints. It is also an important substrate for the production of oxymethylene ethers, which can be used as sustainable fuels and fuel additives or as solvents. The main focus of our research is the conversion of CO and later CO2 with H2 to formaldehyde. The reaction shall be realized in aqueous solution with the help of solid molecular catalysts. Intelligent catalyst design and a profound understanding of the reaction will allow the development of new reaction pathways.
