Synthesis and characterization of electrodes for the electrochemical activation of CO2Copyright: A. Kretzschmar
The electrochemical conversion of the greenhouse gas CO2 to fuels and chemicals is a promising possibility to reduce the emissions of CO2 into the environment. Furthermore it seems achievable to reduce the dependency of fossil energy sources like crude oil by the use of energy from renewable sources and suitable catalysts to synthesize chemicals such as synthesis gas, formic acid or alkanes from CO2 and water. This direct transformation of CO2 to valuable chemicals is generally possible with this method, however it is not yet sufficiently understood to be used at large scale. In this work a GC-MS equipped device for the test of suitable materials should be installed. Therefore catalysts will be prepared using electrospun carbon fibers as a support material. The resulting electrodes will be analyzed by several methods such as gas adsorption experiments, electron microscopy and contact angle measurements. Furthermore their properties in a reactor will be examined, for example electrochemical parameters and the product composition.
