Research interests

Experimental and theoretical research in this Department is focused on electrochemical processes occuring at polarizable solid-liquid and liquid-liquid interfaces with the aim:
  • to establish link between electrocatalytic activity and interfacial structure; structure in this context means the electronic, chemical, and crystallographic structure, as well as particle morphology, size, and organization in larger units,

  • to clarify the reaction mechanism, and to evaluate kinetic and equilibrium parameters of electrochemical redox processes involving (i) molecules with two or more redox centers, (ii) supramolecular complexes (assemblies) and (iii) organometallic compounds,

  • to establish link between electrochemical activity of a molecule, changes of its electronic and chemical structure induced by the electrochemical process, and its chemical, biological, catalytic and other properties,

  • to apply theoretical chemistry methods (especially DFT) to predict electrocatalytic properties of polarizable interfaces, and of electrochemical or photochemical reactivity of molecules, ions, and their aggregates.

Laboratories of the Department are equipped with instruments for stationary and transient electrochemical measurements, interfacial tension measurements, absorption and emission spectroscopy, in-situ spectroelectrochemistry, differential electrochemical mass spectrometry, HPLC, scanning electron microscopy, scanning tunnelling microscopy, Kelvin probe measurements, quartz crystal microbalance, and by an arrangement for sono-electrochemistry and electrochemically generated luminescence. ESCA and XRD instruments for characterization of solid electrode surfaces are located in other laboratories of the Institute. At disposal are further NMR, MS, and X-ray structure analysis for product identification and the determination of chemical structure, and HRTEM for surface morphology.
