Electrochemical Conversion of CO2

Direct electrocatalytic conversion of CO2 to CO using renewable electricity couples the electrolytic splitting of water into hydrogen and oxygen with re-use of CO2. The coupling of the two reactions forms the basis for a promising future one-step process technology for reducing/re-use CO2 emissions in waste gas streams, while delivering valuable chemical products.

What exactly is being done?

This project focuses on key fundamental scientific challenges of this technology. These relate to our understanding of the chemical reaction dynamics of this process, the design and development of novel active and selective process catalyst materials, and their implementation in gas diffusion electrode devices. The project will predict new active and selective metal and non-metal catalyst candidates, will synthesize, characterize, and test these new candidates in electrochemical cells and electrolysis devices. The electrochemical performance of the new materials will also be investigated using novel in-situ methods that will provide information about the active state of the catalysts under reaction conditions.

Expected Results

Project outcomes range from improved understanding of the reaction dynamics, correlations of catalytic activity and catalyst structure, to practical electrochemical performance data in realistic gas diffusion electrodes.
