Porous materials for CO2 absorption

The research, which has received £1.4m of funding from the EPSRC, will see Bath’s Institute for Sustainable Energy and the Environment (I-SEE) work alongside engineers from Bristol and West of England universities to develop materials for use in zero-carbon products.

According to Dr David Fermin from Bristol University, there is currently no effective large-scale technology available for capturing and processing carbon dioxide in this way.

’Conventional approaches to processing CO₂ involve designing catalysts capable of adsorbing and reducing CO₂,’ he said. ’This has proved to be a mighty challenge, particularly in the electrochemical context. In this project, we will investigate composite materials in which adsorption and reduction will take place in different domains integrated at the nanoscale.’

Dr Frank Marken, a lecturer in chemistry at Bath University, said that existing processes rely on separate technology to extract, capture and utilise CO₂. He believes that by combining the processes together, there will be less energy required to drive the CO₂ reduction, making the process more viable.
