Solid state chemistry – mesostructured materials: Juniorprofessor Dr. Mirijam Zobel

Our research interest focusses on the local structure of colloidal particles, solvents and their interfaces. Dissolved clusters and dispersed particles interact with the surrounding solvent molecules. This can impact both, the internal structure of the particle and the molecular arrangement of the solvent molecules. In our workgroup, we look at those interfaces and local structures to understand how the local structures and the restructuring is related to macroscopic system properties.


Solvent restructuring at colloidal interfaces           

Interfaces are of particular interest in various fields including colloid science, catalysis and biomedicine to just name a few. Restructuring within the adjacent materials is taking place and results in modified interfacial properties. ...more

Structure-activity correlation of methanation catalysts

One of the major challenge for a sustainable power supply in the future is the long-term storage of renewable energy. A powerful approach is the power-to-gas concept, which uses excess energy to produce hydrogen via electrolytic water-splitting. The hydrogen can further react with CO2 to methane, in a so called methanation reaction ...more

Correlation of solvent restructuring with the catalytic activity of noble metal nanoparticles

Heterogeneous catalysts are used in more than 90 % of modern industrial syntheses of chemicals and pharmaceuticals. Supported noble metal nanoparticles obtain much attention because they combine the advantages of heterogeneous and homogeneous catalysts. The activity and selectivity of those catalysts is influenced on the one hand by their size and shape, and on the other hand by reaction parameters such as solvent, temperature and pressure ...more


Evolution of crystallinity in nanoparticles

The internal particle structure determines the physico-chemical particle properties, e.g. the photoluminescence. Nevertheless during nanoparticle formation, the atomic structure is not as frequently studied as the particle size itself. We run in-situ X-ray scattering experiments to get atomic insight into molecular precursors and the evolution of crystallinity  ...more

Pair Distribution Function

The pair distribution function (PDF) is a histogram of interatomic distances of the sample. It allows us to study the local and short-range order of materials, whose structures are hard to access by classical X-ray diffraction, i.e. disordered nanoparticles, glasses and liquids ...more

Experiments at synchrotron and neutron scattering facilities

High-quality PDF data is collected during beamtimes at large-scale research facilities, i.e. most frequently synchrotron radiation facilities all around the globe ...more
