Projektbeschreibung
Natürlich und umweltfreundlich: „Photosynthese“ von Brennstoffen im Industriemaßstab
Eine großartige Möglichkeit, das CO2 in der Atmosphäre zu reduzieren, besteht in seiner Abscheidung und Umwandlung in andere kohlenstoffbasierte Chemikalien und hochwertige Brennstoffe. Die CO2-Elektroreduktion, also die Reduktion von CO2 mit Strom, ist eine der vielversprechendsten Technologien – insbesondere wenn dieser Strom aus erneuerbaren Energiequellen erzeugt wird. Das EU-finanzierte Projekt CF-CO2R geht die Herausforderungen derzeitiger Elektrokatalysatoren an, indem es eine kombinierte Kampagne von Experimenten und Modellierung durchführt. Hocheffiziente Elektrokatalysatoren werden die CO2-Elektroreduktion in die Lage versetzen, die Anforderungen der industriellen Umsetzung zu erfüllen. Davon werden sowohl die Umwelt als auch die Wettbewerbsposition der EU profitieren.
Ziel
In the light of rising levels of atmospheric CO2 and associated climate change, the development of advanced techniques for CO2 conversion is of foremost importance. Particularly, many efforts have been made recently to synthesize efficient electrocatalysts for CO2 reduction to carbon fuels using renewable electricity. Nevertheless, to meet the requirement of industrial implementation, even the best performance of these recently developed electrocatalysts must be increased by one order of magnitude. Currently, energy efficiency of CO2 electroreduction is limited by energy-loss in catholyte and transport of CO2 to the cathode surface. The importance of transport limitations will grow as currents approach the higher levels required for industry. The vision for this work is the design of an efficient catholyte-free electrode structure and reactor, in combination with state-of-the-art photovoltaic, that can provide for the industry-ready artificial photosynthesis of carbon fuels. To achieve this goal, we will be dedicated to develop a membrane electrode assembly cell with the design of a catholyte-free flow-through-porous electrode which will allow the incorporation of newly types of nanostructured electrocatalysts and efficient CO2 transfer and conversion into specific carbon fuels such as ethylene or ethanol. Particularly, the proposed research aims include: (i) Development of efficient electrocatalysts that allow the formation of ideal products (ethylene/ethanol); (ii) Enhancement of electrocatalytic activity and stability via system engineering; (iii) Understanding the fundamentals of CO2 electroreduction and cell mechanics to accelerate the development of catholyte-free flow-through-porous electrode for the design of a scalable, high-performance CO2 electroconversion cell through both experiments and theoretical modeling; (iv) Achieving the scalable solar fuels production with CO2 reduction and photovoltaic in tandem.
