Photo-Electrochemical Scanning Probe Microscopy
Helmholtz Young Investigator Research Group
Our research group focuses on material synthesis and nanoscale understanding of solid-liquid interfaces for applications in catalysis and energy conversion. Key catalytic reactions, including CO2 conversion, are challenged by the degradation of the materials employed under operation conditions, performance-limiting inefficiencies at catalyst-electrode interfaces, and limited selectivity and efficiency of the catalysts for multi-electron and proton-coupled transformations.
Deficient nanoscale elucidation of structure-property relationships and dynamic material properties under reaction conditions hamper progress toward the synthesis of the next-generation of material systems.
We address these challenges by employing high spatio-temporal resolution scanning probe microscopy, including atomic force microscopy in liquid phase to decipher in-situ / operando the structural, electronic, and catalytic properties of selected materials under reaction conditions and external stimuli. Combined with a suite of advanced spectroscopic characterization tools, we elucidate nanoscale structure-property relationships and charge-transport phenomena at solid-liquid interfaces. These efforts are combined synergistically with the synthesis of advanced catalytic materials.
