Oral presentation: Chemical Looping CO₂-to-CO Conversion Using Structured Oxygen Carriers

Abstract opening:
Anthropogenic CO₂ emissions are a major contributor to global warming and climate change. Transforming CO₂ from a greenhouse gas into a valuable C₁ feedstock offers a promising pathway to mitigate emissions while enabling sustainable chemical production. Among various utilization strategies, the conversion of CO₂ to carbon monoxide (CO) is particularly attractive, as CO serves as a key intermediate for synthesizing fuels and chemicals such as alcohols, hydrocarbons, and organic acids. This approach not only contributes to closing the carbon loop but also supports the transition toward a circular carbon economy. Several technologies have been developed for CO₂-to-CO conversion, including electrochemical, photochemical, and thermal catalytic processes. Of these, thermal catalytic routes powered by green electricity and green hydrogen stand out for their scalability and operational flexibility. Within this domain, chemical looping has emerged as a particularly promising method…
