High concentration of atmospheric CO2 and energy crisis are two of the major challenges facing our human beings nowadays. One promising technology to tackle these challenges is the solar-driven conversion of CO2 to fuels and chemicals, known as artificial photosynthesis. In this project, we will develop systems which integrate photovoltaics, electrolyzers and fermenters together to convert CO2 to alcohol fuels with solar radiation as the only energy input. Perovskites photovoltaics will be employed to produce renewable electricity that is used for the generation of syngas via electrolysis. The syngas will be introduced to the fermenters containing microorganism such as C. autoethanogenum and C. kluyveri to produce alcohol fuels. This fermentation process also serves as an effective separation technique by converting gas products to liquid fuels. The entire system is expected to have remarkable energy efficiency, high production rate and robustness.
Quelles sont les particularités de ce projet?
Solar-driven CO2 reduction to alcohols have been studied in photocatalysis and photo-electrochemistry. However, the energetic efficiency is far from satisfactory. Here, we employ microorganism to convert syngas to alcohol products to circumvent the energy barrier required for the direct reduction of CO2 to alcohol. This innovative tandem electro-bio method will enable exceptionally high energetic efficiency. Moreover, our system will be only dependent earth abundant materials and will employ the new-generation photovoltaics based on perovskites. These new aspects will not only push the efficiency to a new level, but also bring chemists and microbiologist together to address our concerns on energy crisis and climate change.
This project will start on 1st March 2020
