Microwave-synthesis of carbon materials
Naturally occurring organic acids provide the potential to serve as resource for functional carbon nanomaterials. Their chemistry at high temperatures is complex but facilitates the targeted synthesis of particulate compounds with specific structural and physical properties. These are of great importance for charge-transfer processes, for example, in catalysis. In our approach we correlate the optical and electronic properties of such particulate compounds with their structural features. Based on these insights we develop new colloidal systems for the application in charge-transfer processes.
Laser-assisted Carbonization and Patterning
Using high-precision laser-patterning techniques we investigate new carbonization and modification methods for the targeted preparation of electronic devices based on renewable molecular precursors. For example, we use pre-condensed compounds for the controlled synthesis and deposition of extended, highly conductive carbon networks onto different substrates by CO2-Laser reduction. Materials properties such as conductivity, porosity, or active surface area can be tuned by selection of the precursors and the synthesis parameters. Thereby, we create substrate-supported carbon-based materials with specific properties for electronic devices.
