The POWER CO₂ Days! | Sept 7–9, 2026 | Lyon
Day 3: Hybrid Approaches
Natural metalloenzymes are often the most proficient catalysts available for activating challenging small molecules like CO₂, CO, and H₂. We are thrilled to welcome Christine Cavazza, Head of the Bioenergy & Environment Team at CEA Grenoble, to discuss their immense potential in sustainable energy technologies and learn about her latest research breakthroughs.
In the search for new catalytic devices, redox metalloenzymes stand out due to their high performance under mild conditions, reliance on earth-abundant metals, and minimal overpotential. Despite their oxygen sensitivity and structural complexity, they are excellent candidates for developing sustainable, bio-electrocatalytic systems.
A prime example is carbon monoxide dehydrogenase (CODH), which reversibly catalyzes the reduction of CO₂ to CO at phenomenal rates. To harness this for efficient CO₂-to-CO interconversion, Christine’s team developed a multidisciplinary approach combining biochemistry, custom electrode design, and deep eutectic solvents.
During her plenary lecture, Christine will detail how recombinant CODH—immobilized on modified carbon nanotuves electrodes—achieves selective CO₂/CO interconversion with remarkable turnover frequencies. She will also showcase how this enzyme was successfully integrated into a nanohybrid device to drive an energy-efficient water-gas shift reaction.
