The Becker research group - Professorship of Physical Chemistry - focuses on the theoretical and experimental investigation of structures and dynamics in molecules and complex interfaces.
Nanoparticles are systematically produced from complexes using electrochemical processes. The electrochemically produced transition metal nanoparticles are analysed by vibrational spectroscopy and electron spectroscopy. In addition, the redox processes taking place are investigated using cyclovoltametry and impedance. Extending these methods to include transmission electron microscopy allows conclusions to be drawn about shape and size effects and then enables a correspondingly rapid insight into the product clusters and then a rapid adjustment of the electrochemical parameters.
Transition metal oxide particles are the main materials investigated by the working group. Other materials that are being analysed are germanium and silicon oxide microneedles and their interfaces under reactive conditions as well as iron oxide particles from solvothermal syntheses. The experimental results are supported by initio methods such as Gaussian and ADF.
