Research Associate for the Project “BioValCat” § 28 Subsection 3 HmbHG

Your responsibilities

Duties include academic services in the project named above. Research associates may also pursue independent research and further academic qualifications. They may also pursue doctoral studies outside of working duties.

The five-year project “BioValCat” (Enhanced Biomass Valorisation by Engineering of Polyoxometalate Catalysts), funded by the ERC Consolitator Grant 2022, aims to enable 100% carbon efficiency from complex biomass by developing innovative POM catalyst-solvent systems for aerobic and anaerobic applications and to develop this into an innovative and widely applicable process technology.

Polyoxometalates (POMs), as a unique class of anionic polynuclear metal-oxo clusters with high structural diversity at the atomic level, are highly promising candidates for the selective oxidation of biomass to organic acids. In the field of homogeneously catalysed, selective biomass conversion, POMs are already used intensively. One example for the potential of POMs is the already commercialised OxFA process, in which biomass is oxidatively converted to formic acid in aqueous systems.

Recent research has shown that POM catalysts can completely suppress the undesired total oxidation to CO2 under oxidative conditions when methanol is used as a (co-)solvent. Manipulating molecular catalysts such as POMs in solution by tuning the solvent properties and gas atmospheres introduces a new paradigm in homogeneous-catalysed biomass valorisation technologies. The proposed BioValCat project aims for developing this technology towards an industrial viable biomass valorisation process by laying the foundations for a scalable, safe and economic process for the oxidation of biomass to valuable carboxylic acid esters.

A particular focus of the position advertised here will be on the synthesis and characterisation of promising POM catalyst structures. The goal is to overcome the challenges of using POMs in classical homogeneous catalysis like expensive product isolation and catalyst recycling accompanied by precipitation or undesired POM reactions with substrates or intermediates. The aim is to combine high catalytic activity and selectivity of POMs with ease of handling and facile separation. The prepared POM catalysts will be characterized in depth to understand the structure/composition of the obtained materials and to develop material optimisation concepts for enhanced catalytic performance. Appropriate analytical methods (e.g. ICP-OES, XRF, XRD, FT-IR, TGA, UV-Vis, Raman, EPR and NMR) will be used to characterise the POM catalysts and to understand the POM-solvent interactions.
